feat(rust): Implement RustCargoLockParser and RustFingerprintScanner

- Added RustCargoLockParser to parse Cargo.lock files and extract package information.
- Introduced RustFingerprintScanner to scan for Rust fingerprint records in JSON files.
- Created test fixtures for Rust language analysis, including Cargo.lock and fingerprint JSON files.
- Developed tests for RustLanguageAnalyzer to ensure deterministic output based on provided fixtures.
- Added expected output files for both simple and signed Rust applications.

 - Documentation (this plan) linked from `TASKS.md` notes for discoverability.
+
+## 11. 2025-10-22 Progress Notes
+
+- Implemented `IVexAttestationVerifier`/`VexAttestationVerifier` with structural validation (subject/predicate checks, digest comparison, Rekor probes) and diagnostics map.
+- Added `VexAttestationVerificationOptions` (RequireTransparencyLog, AllowOfflineTransparency, MaxClockSkew) and wired configuration through WebService DI.
+- Created `VexAttestationMetrics` (`excititor.attestation.verify_total`, `excititor.attestation.verify_duration_seconds`) and hooked into verification flow with component/rekor tags.
+- `VexAttestationClient.VerifyAsync` now delegates to the verifier; DI registers metrics + verifier via `AddVexAttestation`.
+- Added unit coverage in `VexAttestationVerifierTests` (happy path, digest mismatch, offline Rekor) and updated client/export/webservice stubs to new verification signature.

+- **Progress (2025-10-22):** Build-info decoder shipped with DWARF-string fallback for `vcs.*` markers, plus cached metadata keyed by binary length/timestamp. Added Go test fixtures covering build-info and DWARF-only binaries with deterministic goldens; analyzer now emits `go.dwarf` evidence alongside `go.buildinfo` metadata to feed downstream provenance rules. Completed stripped-binary heuristics with deterministic `golang::bin::sha256` components and a new `stripped` fixture to guard quiet-provenance behaviour.

 - **Scope:** Parse `*.deps.json`, `runtimeconfig.json`, assembly metadata, and RID-specific assets; correlate with native dependencies.
