Add tests for SBOM generation determinism across multiple formats

- Created `StellaOps.TestKit.Tests` project for unit tests related to determinism.
- Implemented `DeterminismManifestTests` to validate deterministic output for canonical bytes and strings, file read/write operations, and error handling for invalid schema versions.
- Added `SbomDeterminismTests` to ensure identical inputs produce consistent SBOMs across SPDX 3.0.1 and CycloneDX 1.6/1.7 formats, including parallel execution tests.
- Updated project references in `StellaOps.Integration.Determinism` to include the new determinism testing library.

+# Console Forensics (stub)
+
+> Status: BLOCKED awaiting timeline/evidence viewer assets and payloads from Console Guild. Follow this outline when assets arrive.
+
+## Scope
+- Timeline explorer, evidence viewer, attestation verifier flows.
+- Imposed rule banner and offline-friendly walkthroughs.
+- Troubleshooting section with deterministic repro steps.
+
+## Pending inputs
+- Deterministic captures (command-rendered or approved screenshots) for timeline and evidence viewer states.
+- Sample NDJSON/JSON payloads for evidence/attestation, with hashes.
+- Error taxonomy and retry/backoff guidance for user-facing errors.
+
+## Determinism checklist
+- Hash all captures/payloads in co-located `SHA256SUMS` when provided.
+- Use UTC timestamps and stable ordering in tables and examples.
+
+## Outline
+1. Overview + banner
+2. Timeline explorer walkthrough (filters, drilldowns)
+3. Evidence viewer (attestations, signatures, DSSE bundle) examples
+4. Attestation verifier steps and expected outputs
+5. Troubleshooting + error taxonomy
+6. Offline/air-gap operation steps
+7. Verification (hash check + replay commands)
