master bc4318ef97 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.

Purpose

Track Link-Not-Merge aggregation and overlay pipelines.

Metrics

aggregation_ingest_latency_seconds{tenant,source,status}
aggregation_conflict_total{tenant,advisory,product,reason}
aggregation_overlay_cache_hits_total, aggregation_overlay_cache_misses_total
aggregation_vex_gate_total{tenant,status}
aggregation_queue_depth{tenant}

Traces

Span: aggregation.process
Attributes: tenant, advisory, product, vex_status, source_kind, overlay_version, cache_hit

Logs

tenant, advisory, product, vex_status
decision (merged, suppressed, dropped)
reason, duration_ms, trace_id

SLOs

Ingest latency p95 < 500ms per statement.
Overlay cache hit rate > 80%.
Error rate < 0.1% over 10 minutes.

Alerts

HighConflictRate: aggregation_conflict_total delta > 100 per minute.
QueueBacklog: aggregation_queue_depth > 10k for 5 minutes.
LowCacheHit: cache hit rate < 60% for 10 minutes.

Offline posture

Export metrics to local Prometheus scrape.
Deterministic ordering preserved; cache warmers seeded from bundled fixtures.
