kjh2064 97444c932f Workstream I: Implement VS-04 Audit Trail (Immutable events + GDPR compliance)
- 2 audit query endpoints: GET /audit/events (filtered), GET /audit/events/{id}
- 1 GDPR endpoint: POST /compliance/gdpr-request (right-to-be-forgotten)
- Immutable INSERT-only audit_events table with correlation_id
- GDPR redaction (soft delete): anonymize personal data, keep audit trail
- Regulatory compliance: FSS 7-year retention, GDPR Article 17, PCI-DSS logging
- Integration: Event subscribers for all model operations
- Schema: Append-only with PIT tracking, evidence links (S3 artifacts)
- Tests: 6+ integration scenarios (insert, query, GDPR redaction)
- AGENTS.md v16.0 13/13 compliance 

Closes workstream I (Phase 2 implementation, compliance layer).
