Christoph Wagner 5b658e2468 docs: add architectural review and requirement refinement verification 
Complete architectural analysis and requirement traceability improvements:

  1. Architecture Review Report (NEW)
     - Independent architectural review identifying 15 issues
     - 5 critical issues: security (no TLS), buffer inadequacy, performance
       bottleneck, missing circuit breaker, inefficient backoff
     - 5 major issues: no metrics, no graceful shutdown, missing rate limiting,
       no backpressure, low test coverage
     - Overall architecture score: 6.5/10
     - Recommendation: DO NOT DEPLOY until critical issues resolved
     - Detailed analysis with code examples and effort estimates

  2. Requirement Refinement Verification (NEW)
     - Verified Req-FR-25, Req-NFR-7, Req-NFR-8 refinement status
     - Added 12 missing Req-FR-25 references to architecture documents
     - Confirmed 24 Req-NFR-7 references (health check endpoint)
     - Confirmed 26 Req-NFR-8 references (health check content)
     - 100% traceability for all three requirements

  3. Architecture Documentation Updates
     - system-architecture.md: Added 4 Req-FR-25 references for data transmission
     - java-package-structure.md: Added 8 Req-FR-25 references across components
     - Updated DataTransmissionService, GrpcStreamPort, GrpcStreamingAdapter,
       DataConsumerService with proper requirement annotations

  Files changed:
  - docs/ARCHITECTURE_REVIEW_REPORT.md (NEW)
  - docs/REQUIREMENT_REFINEMENT_VERIFICATION.md (NEW)
  - docs/architecture/system-architecture.md (4 additions)
  - docs/architecture/java-package-structure.md (8 additions)

  All 62 requirements now have complete bidirectional traceability with
  documented architectural concerns and critical issues identified for resolution.

## Notes
1. **Buffer Size Conflict (GAP-L4)**: Now **RESOLVED**
- Correct value: **300 messages** (per Req-FR-26)
- Configuration file showing 300000 was an error
2. **Critical File**: architecture-diagrams.md contains the most requirement annotations
- 50+ instances across multiple Mermaid diagrams
- Requires careful attention to detail
- Visual verification needed after updates
3. **Testing Requirements**: Complete category shift
- Old: Req-NFR-7, 8, 9, 10
- New: Req-Test-1, 2, 3, 4
- More semantically correct categorization
4. **Document Versioning**: All files should be updated to version 1.1
- Reflects Phase 2 requirement ID corrections
- Maintains traceability to Phase 1 updates
