feat: Enhance SBOM composition with policy findings and update CycloneDX package

- Added `PolicyFindings` property to `SbomCompositionRequest` to include policy findings in SBOM. - Implemented `NormalizePolicyFindings` method to process and validate policy findings. - Updated `SbomCompositionRequest.Create` method to accept policy findings as an argument. - Upgraded CycloneDX.Core package from version 5.1.0 to 10.0.1. - Marked several tasks as DONE in TASKS.md, reflecting completion of SBOM-related features. - Introduced telemetry metrics for Go analyzer to track heuristic fallbacks. - Added performance benchmarks for .NET and Go analyzers. - Created new test fixtures for .NET applications, including dependencies and runtime configurations. - Added licenses and nuspec files for logging and toolkit packages used in tests. - Implemented `SbomPolicyFinding` record to encapsulate policy finding details and normalization logic.

+## Sprint LA3 — Go Analyzer Benchmark Notes (2025-10-22)
+
+- Scenario `go_buildinfo_fixture` captures our Go analyzer running against the basic build-info fixture. The Oct 23 baseline (`baseline.csv`) shows a mean duration of **35.03 ms** (p95 136.55 ms, max 170.16 ms) over 5 iterations on the current rig; earlier Oct 21 measurement recorded **4.02 ms** mean when the analyzer was profiled on the warm perf runner.
+- Comparative run against Syft v1.29.1 on the same fixture (captured 2025-10-21) reported a mean of **5.18 ms** (p95 18.64 ms, max 23.51 ms); raw measurements live in `go/syft-comparison-20251021.csv`.
+- Bench command (from repo root):\
+  `dotnet run --project bench/Scanner.Analyzers/StellaOps.Bench.ScannerAnalyzers/StellaOps.Bench.ScannerAnalyzers.csproj -- --config bench/Scanner.Analyzers/config.json --out bench/Scanner.Analyzers/baseline.csv`
+
+## Sprint LA4 — .NET Analyzer Benchmark Notes (2025-10-23)
+
+- Scenario `dotnet_multirid_fixture` exercises the .NET analyzer against the multi-RID test fixture that merges two applications and four runtime identifiers. Latest baseline run (Release build, 5 iterations) records a mean duration of **29.19 ms** (p95 106.62 ms, max 132.30 ms) with a stable component count of 2.
+- Syft v1.29.1 scanning the same fixture (`syft scan dir:…`) averaged **1 546 ms** (p95 ≈2 100 ms, max ≈2 100 ms) while also reporting duplicate packages; raw numbers captured in `dotnet/syft-comparison-20251023.csv`.
+- The new scenario is declared in `bench/Scanner.Analyzers/config.json`; rerun the bench command above after rebuilding analyzers to refresh baselines and comparison data.

 ## Dependencies

  - Tests verifying dual runtimeconfig merge logic.
  - Guidance for Policy on license propagation from NuGet metadata.
 - **Progress (2025-10-22):** Completed task 10-305A with a deterministic deps/runtimeconfig ingest pipeline producing `pkg:nuget` components across RID targets. Added dotnet fixture + golden output to the shared harness, wired analyzer plugin availability, and surfaced RID metadata in component records for downstream emit/diff work. License provenance and quiet flagging now ride through the shared helpers (task 10-307D), including nuspec license expression/file ingestion, manifest provenance tagging, and concurrency-safe file metadata caching with new parallel tests.
+- **Progress (2025-10-23):** Landed determinism + benchmark coverage (task 10-308D) via the new `multi` fixture, golden outputs, and bench scenario wired into `baseline.csv`, plus Syft comparison data. Packaged the .NET plug-in for restart-only distribution (task 10-309D), verified manifest copy into `plugins/scanner/analyzers/lang/`, and refreshed `docs/24_OFFLINE_KIT.md` with updated Offline Kit instructions.

 ## Sprint LA5 — Rust Analyzer & Binary Fingerprinting (Tasks 10-306, 10-307, 10-308, 10-309 subset)
 - **Scope:** Detect crates via metadata in `.fingerprint`, Cargo.lock fragments, or embedded `rustc` markers; robust fallback to binary hash classification.
