feat(crypto): Complete Phase 2 - Configuration-driven crypto architecture with 100% compliance

## Summary

This commit completes Phase 2 of the configuration-driven crypto architecture, achieving
100% crypto compliance by eliminating all hardcoded cryptographic implementations.

## Key Changes

### Phase 1: Plugin Loader Infrastructure
- **Plugin Discovery System**: Created StellaOps.Cryptography.PluginLoader with manifest-based loading
- **Configuration Model**: Added CryptoPluginConfiguration with regional profiles support
- **Dependency Injection**: Extended DI to support plugin-based crypto provider registration
- **Regional Configs**: Created appsettings.crypto.{international,russia,eu,china}.yaml
- **CI Workflow**: Added .gitea/workflows/crypto-compliance.yml for audit enforcement

### Phase 2: Code Refactoring
- **API Extension**: Added ICryptoProvider.CreateEphemeralVerifier for verification-only scenarios
- **Plugin Implementation**: Created OfflineVerificationCryptoProvider with ephemeral verifier support
  - Supports ES256/384/512, RS256/384/512, PS256/384/512
  - SubjectPublicKeyInfo (SPKI) public key format
- **100% Compliance**: Refactored DsseVerifier to remove all BouncyCastle cryptographic usage
- **Unit Tests**: Created OfflineVerificationProviderTests with 39 passing tests
- **Documentation**: Created comprehensive security guide at docs/security/offline-verification-crypto-provider.md
- **Audit Infrastructure**: Created scripts/audit-crypto-usage.ps1 for static analysis

### Testing Infrastructure (TestKit)
- **Determinism Gate**: Created DeterminismGate for reproducibility validation
- **Test Fixtures**: Added PostgresFixture and ValkeyFixture using Testcontainers
- **Traits System**: Implemented test lane attributes for parallel CI execution
- **JSON Assertions**: Added CanonicalJsonAssert for deterministic JSON comparisons
- **Test Lanes**: Created test-lanes.yml workflow for parallel test execution

### Documentation
- **Architecture**: Created CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md master plan
- **Sprint Tracking**: Created SPRINT_1000_0007_0002_crypto_refactoring.md (COMPLETE)
- **API Documentation**: Updated docs2/cli/crypto-plugins.md and crypto.md
- **Testing Strategy**: Created testing strategy documents in docs/implplan/SPRINT_5100_0007_*

## Compliance & Testing

- ✅ Zero direct System.Security.Cryptography usage in production code
- ✅ All crypto operations go through ICryptoProvider abstraction
- ✅ 39/39 unit tests passing for OfflineVerificationCryptoProvider
- ✅ Build successful (AirGap, Crypto plugin, DI infrastructure)
- ✅ Audit script validates crypto boundaries

## Files Modified

**Core Crypto Infrastructure:**
- src/__Libraries/StellaOps.Cryptography/CryptoProvider.cs (API extension)
- src/__Libraries/StellaOps.Cryptography/CryptoSigningKey.cs (verification-only constructor)
- src/__Libraries/StellaOps.Cryptography/EcdsaSigner.cs (fixed ephemeral verifier)

**Plugin Implementation:**
- src/__Libraries/StellaOps.Cryptography.Plugin.OfflineVerification/ (new)
- src/__Libraries/StellaOps.Cryptography.PluginLoader/ (new)

**Production Code Refactoring:**
- src/AirGap/StellaOps.AirGap.Importer/Validation/DsseVerifier.cs (100% compliant)

**Tests:**
- src/__Libraries/__Tests/StellaOps.Cryptography.Plugin.OfflineVerification.Tests/ (new, 39 tests)
- src/__Libraries/__Tests/StellaOps.Cryptography.PluginLoader.Tests/ (new)

**Configuration:**
- etc/crypto-plugins-manifest.json (plugin registry)
- etc/appsettings.crypto.*.yaml (regional profiles)

**Documentation:**
- docs/security/offline-verification-crypto-provider.md (600+ lines)
- docs/implplan/CRYPTO_CONFIGURATION_DRIVEN_ARCHITECTURE.md (master plan)
- docs/implplan/SPRINT_1000_0007_0002_crypto_refactoring.md (Phase 2 complete)

## Next Steps

Phase 3: Docker & CI/CD Integration
- Create multi-stage Dockerfiles with all plugins
- Build regional Docker Compose files
- Implement runtime configuration selection
- Add deployment validation scripts

+# StellaOps.Cryptography.Plugin.OfflineVerification
+
+Cryptographic provider for offline/air-gapped environments using .NET BCL cryptography.
+
+## Overview
+
+The `OfflineVerificationCryptoProvider` wraps `System.Security.Cryptography` in the `ICryptoProvider` abstraction, enabling configuration-driven crypto while maintaining offline verification capabilities without external dependencies.
+
+## Supported Algorithms
+
+### Signing & Verification
+- **ECDSA**: ES256 (P-256/SHA-256), ES384 (P-384/SHA-384), ES512 (P-521/SHA-512)
+- **RSA PKCS1**: RS256, RS384, RS512
+- **RSA-PSS**: PS256, PS384, PS512
+
+### Content Hashing
+- **SHA-2**: SHA-256, SHA-384, SHA-512 (supports both `SHA-256` and `SHA256` formats)
+
+## When to Use
+
+Use `OfflineVerificationCryptoProvider` when:
+
+1. **Offline/Air-Gapped Environments**: Systems without network access or external cryptographic services
+2. **Default Cryptography**: Standard NIST-approved algorithms without regional compliance requirements
+3. **Container Scanning**: AirGap module, Scanner module, and other components that need deterministic signing
+4. **Testing**: Local development and testing without hardware security modules
+
+**Do NOT use when:**
+- Regional compliance required (eIDAS, GOST R 34.10, SM2) - use specialized plugins instead
+- FIPS 140-2 Level 3+ hardware security required - use HSM plugins
+- Key management by external providers - use cloud KMS plugins (AWS KMS, Azure Key Vault, etc.)
+
+## Usage
+
+### Basic Hashing
+
+```csharp
+using StellaOps.Cryptography;
+using StellaOps.Cryptography.Plugin.OfflineVerification;
+
+var provider = new OfflineVerificationCryptoProvider();
+var hasher = provider.GetHasher("SHA-256");
+var hash = hasher.ComputeHash(data);
+```
+
+### Signing with Stored Keys
+
+```csharp
+var provider = new OfflineVerificationCryptoProvider();
+
+// Add key to provider
+var signingKey = new CryptoSigningKey(
+    reference: new CryptoKeyReference("my-key"),
+    algorithmId: "ES256",
+    privateParameters: ecParameters,
+    createdAt: DateTimeOffset.UtcNow);
+
+provider.UpsertSigningKey(signingKey);
+
+// Get signer and sign data
+var signer = provider.GetSigner("ES256", new CryptoKeyReference("my-key"));
+var signature = await signer.SignAsync(data);
+```
+
+### Ephemeral Verification (New in 1.0)
+
+For scenarios where you only have a public key (e.g., DSSE verification, JWT verification):
+
+```csharp
+var provider = new OfflineVerificationCryptoProvider();
+
+// Public key in SubjectPublicKeyInfo (DER-encoded) format
+byte[] publicKeyBytes = ...; // From certificate, JWKS, or inline
+
+// Create ephemeral verifier
+var verifier = provider.CreateEphemeralVerifier("PS256", publicKeyBytes);
+
+// Verify signature
+var isValid = await verifier.VerifyAsync(message, signature);
+```
+
+**Supported Algorithms for Ephemeral Verification:**
+- ECDSA: ES256, ES384, ES512
+- RSA PKCS1: RS256, RS384, RS512
+- RSA-PSS: PS256, PS384, PS512
+
+**Key Format:**
+- Public keys must be in **SubjectPublicKeyInfo** (SPKI) format (DER-encoded)
+- This is the standard format used in X.509 certificates, JWKs, and TLS
+
+### Dependency Injection
+
+```csharp
+services.AddStellaOpsCryptoFromConfiguration(configuration);
+```
+
+Ensure `etc/crypto-plugins-manifest.json` includes:
+
+```json
+{
+  "id": "offline-verification",
+  "name": "OfflineVerificationCryptoProvider",
+  "assembly": "StellaOps.Cryptography.Plugin.OfflineVerification.dll",
+  "type": "StellaOps.Cryptography.Plugin.OfflineVerification.OfflineVerificationCryptoProvider",
+  "capabilities": [
+    "signing:ES256", "signing:ES384", "signing:ES512",
+    "signing:RS256", "signing:RS384", "signing:RS512",
+    "signing:PS256", "signing:PS384", "signing:PS512",
+    "hashing:SHA-256", "hashing:SHA-384", "hashing:SHA-512",

+    "verification:RS256", "verification:RS384", "verification:RS512",
+    "verification:PS256", "verification:PS384", "verification:PS512"
+  ],

+  "compliance": ["NIST", "offline-airgap"],
+  "platforms": ["linux", "windows", "osx"],
+  "priority": 45,
+  "enabledByDefault": true
+}
+```
+
+## API Reference
+
+### ICryptoProvider.CreateEphemeralVerifier
+
+```csharp
+ICryptoSigner CreateEphemeralVerifier(string algorithmId, ReadOnlySpan<byte> publicKeyBytes)
+```
+
+Creates a verification-only signer from raw public key bytes. Useful for:
+- DSSE envelope verification with inline public keys
+- JWT/JWS verification without key persistence
+- Ad-hoc signature verification in offline scenarios
+
+**Parameters:**
+- `algorithmId`: Algorithm identifier (ES256, RS256, PS256, etc.)
+- `publicKeyBytes`: Public key in SubjectPublicKeyInfo format (DER-encoded)
+
+**Returns:**
+- `ICryptoSigner` instance with `VerifyAsync` support only
+- `SignAsync` throws `NotSupportedException`
+- `KeyId` returns `"ephemeral"`
+- `AlgorithmId` returns the specified algorithm
+
+**Throws:**
+- `NotSupportedException`: If algorithm not supported or public key format invalid
+
+## Implementation Details
+
+### Internal Architecture
+
+```
+OfflineVerificationCryptoProvider (ICryptoProvider)
+├── BclHasher (ICryptoHasher)
+│   └── System.Security.Cryptography.SHA256/384/512
+├── EcdsaSigner (ICryptoSigner)
+│   └── System.Security.Cryptography.ECDsa
+├── RsaSigner (ICryptoSigner)
+│   └── System.Security.Cryptography.RSA
+├── EcdsaEphemeralVerifier (ICryptoSigner)
+│   └── System.Security.Cryptography.ECDsa (verification-only)
+└── RsaEphemeralVerifier (ICryptoSigner)
+    └── System.Security.Cryptography.RSA (verification-only)
+```
+
+### Plugin Boundaries
+
+**Allowed** within this plugin:
+- Direct usage of `System.Security.Cryptography` (internal implementation)
+- Creation of `ECDsa`, `RSA`, `SHA256`, `SHA384`, `SHA512` instances
+- Key import/export operations
+
+**Not allowed** outside this plugin:
+- Direct crypto library usage in production code
+- All consumers must use `ICryptoProvider` abstraction
+
+This boundary is enforced by:
+- `scripts/audit-crypto-usage.ps1` - Static analysis
+- `.gitea/workflows/crypto-compliance.yml` - CI validation
+
+## Testing
+
+Run unit tests:
+
+```bash
+dotnet test src/__Libraries/__Tests/StellaOps.Cryptography.Plugin.OfflineVerification.Tests
+```
+
+**Test Coverage:**
+- 39 unit tests covering all algorithms and scenarios
+- Provider capability matrix validation
+- Known-answer tests for SHA-256/384/512
+- ECDSA and RSA signing/verification roundtrips
+- Ephemeral verifier creation and usage
+- Error handling (unsupported algorithms, tampered data)
+
+## Performance
+
+The abstraction layer is designed to be zero-cost:
+- No heap allocations in hot paths
+- Direct delegation to .NET BCL primitives
+- `ReadOnlySpan<byte>` for memory efficiency
+
+Benchmark results should match direct `System.Security.Cryptography` usage within measurement error.
+
+## Security Considerations
+
+1. **Key Storage**: This provider stores keys in-memory only. For persistent key storage, integrate with a key management system.
+
+2. **Ephemeral Verification**: Public keys for ephemeral verification are not cached or validated against a trust store. Callers must perform their own trust validation.
+
+3. **Algorithm Hardening**:
+   - RSA key sizes: 2048-bit minimum recommended
+   - ECDSA curves: Only NIST P-256/384/521 supported
+   - Hash algorithms: SHA-2 family only (SHA-1 explicitly NOT supported)
+
+4. **Offline Trust**: In offline scenarios, establish trust through:
+   - Pre-distributed public key fingerprints
+   - Certificate chains embedded in airgap bundles
+   - Out-of-band key verification
+
+## Compliance
+
+- **NIST FIPS 186-4**: ECDSA with approved curves (P-256, P-384, P-521)
+- **NIST FIPS 180-4**: SHA-256, SHA-384, SHA-512
+- **RFC 8017**: RSA PKCS#1 v2.2 (RSASSA-PKCS1-v1_5 and RSASSA-PSS)
+- **RFC 6979**: Deterministic ECDSA (when used with BouncyCastle fallback)
+
+**Not compliant with:**
+- eIDAS (European digital signature standards) - use eIDAS plugin
+- GOST R 34.10-2012 (Russian cryptographic standards) - use CryptoPro plugin
+- SM2/SM3/SM4 (Chinese cryptographic standards) - use SM plugin

+# StellaOps.TestKit
+
+Test infrastructure and fixtures for StellaOps projects. Provides deterministic time/random, canonical JSON assertions, snapshot testing, database fixtures, and OpenTelemetry capture.
+
+## Features
+
+### Deterministic Time
+```csharp
+using StellaOps.TestKit.Time;
+
+// Create a clock at a fixed time
+var clock = new DeterministicClock();
+var now = clock.UtcNow; // 2025-01-01T00:00:00Z
+
+// Advance time
+clock.Advance(TimeSpan.FromMinutes(5));
+
+// Or use helpers
+var clock2 = DeterministicClockExtensions.AtTestEpoch();
+var clock3 = DeterministicClockExtensions.At("2025-06-15T10:30:00Z");
+```
+
+### Deterministic Random
+```csharp
+using StellaOps.TestKit.Random;
+
+// Create deterministic RNG with standard test seed (42)
+var rng = DeterministicRandomExtensions.WithTestSeed();
+
+// Generate reproducible values
+var number = rng.Next(1, 100);
+var text = rng.NextString(10);
+var item = rng.PickOne(new[] { "a", "b", "c" });
+```
+
+### Canonical JSON Assertions
+```csharp
+using StellaOps.TestKit.Json;
+
+// Assert JSON equality (ignores formatting)
+CanonicalJsonAssert.Equal(expectedJson, actualJson);
+
+// Assert object equivalence
+CanonicalJsonAssert.EquivalentObjects(expectedObj, actualObj);
+
+// Hash-based regression testing
+var hash = CanonicalJsonAssert.ComputeHash(json);
+CanonicalJsonAssert.MatchesHash("abc123...", json);
+```
+
+### Snapshot Testing
+```csharp
+using StellaOps.TestKit.Snapshots;
+
+public class MyTests
+{
+    [Fact]
+    public void TestOutput()
+    {
+        var output = GenerateSomeOutput();
+
+        // Compare against __snapshots__/test_output.txt
+        var snapshotPath = SnapshotHelper.GetSnapshotPath("test_output");
+        SnapshotHelper.VerifySnapshot(output, snapshotPath);
+    }
+
+    [Fact]
+    public void TestJsonOutput()
+    {
+        var obj = new { Name = "test", Value = 42 };
+
+        // Compare JSON serialization
+        var snapshotPath = SnapshotHelper.GetSnapshotPath("test_json", ".json");
+        SnapshotHelper.VerifyJsonSnapshot(obj, snapshotPath);
+    }
+}
+
+// Update snapshots: set environment variable UPDATE_SNAPSHOTS=1
+```
+
+### PostgreSQL Fixture
+```csharp
+using StellaOps.TestKit.Fixtures;
+using Xunit;
+
+[Collection("Postgres")]
+public class DatabaseTests
+{
+    private readonly PostgresFixture _postgres;
+
+    public DatabaseTests(PostgresFixture postgres)
+    {
+        _postgres = postgres;
+    }
+
+    [Fact]
+    public async Task TestQuery()
+    {
+        // Use connection string
+        await using var conn = new Npgsql.NpgsqlConnection(_postgres.ConnectionString);
+        await conn.OpenAsync();
+
+        // Execute SQL
+        await _postgres.ExecuteSqlAsync("CREATE TABLE test (id INT)");
+
+        // Create additional databases
+        await _postgres.CreateDatabaseAsync("otherdb");
+    }
+}
+```
+
+### Valkey/Redis Fixture
+```csharp
+using StellaOps.TestKit.Fixtures;
+using Xunit;
+
+[Collection("Valkey")]
+public class CacheTests
+{
+    private readonly ValkeyFixture _valkey;
+
+    public CacheTests(ValkeyFixture valkey)
+    {
+        _valkey = valkey;
+    }
+
+    [Fact]
+    public void TestCache()
+    {
+        var connectionString = _valkey.ConnectionString;
+        // Use with your Redis/Valkey client
+    }
+}
+```
+
+### OpenTelemetry Capture
+```csharp
+using StellaOps.TestKit.Telemetry;
+
+[Fact]
+public void TestTracing()
+{
+    using var otel = new OTelCapture("my-service");
+
+    // Code that emits traces
+    using (var activity = otel.ActivitySource.StartActivity("operation"))
+    {
+        activity?.SetTag("key", "value");
+    }
+
+    // Assert traces
+    otel.AssertActivityExists("operation");
+    otel.AssertActivityHasTag("operation", "key", "value");
+
+    // Get summary for debugging
+    Console.WriteLine(otel.GetTraceSummary());
+}
+```
+
+## Usage in Tests
+
+Add to your test project:
+```xml
+<ItemGroup>
+  <ProjectReference Include="..\..\__Libraries\StellaOps.TestKit\StellaOps.TestKit.csproj" />
+</ItemGroup>
+```
+
+## Design Principles
+
+- **Determinism**: All utilities produce reproducible results
+- **Offline-first**: No network dependencies (uses Testcontainers for local infrastructure)
+- **Minimal dependencies**: Only essential packages
+- **xUnit-friendly**: Works seamlessly with xUnit fixtures and collections
