jordan d3a88585fe feat: Phase 6 UAT - Admission control, HLC recency, cluster coordination

This commit includes comprehensive work on Phase 6 features:

## Admission Control (Phase 6 admission middleware)
- AdmissionStore implementation backed by TrustRankStore
- PoW verification with tier-based difficulty computation
- Trust tier progression (Newcomer → Established → Trusted → Authority)
- API integration with admission status endpoints

## HLC Recency Lens (Phase 6C)
- HlcRecencyLens for distributed system ordering
- Hybrid logical clock integration with causality preservation

## Cluster Coordination (Phase 6C)
- Multi-node cluster tests (availability, partition tolerance)
- CRDT convergence tests for anti-entropy sync
- Gateway handler improvements

## Aphoria Code Linter (Phase 2A)
- RFC/OWASP corpus builders with network fetching and caching
- Concept hierarchy with auto-alias creation on conflict detection
- Multiple security extractors (TLS, JWT, CORS, secrets, rate limiting)

## Code Organization
- Split large files into modules to comply with 500-line limit
- Improved test organization with separate test modules
- Fixed rkyv serialization for EigenTrustState (AgentScore struct)

Phase 6 UAT Results

Last Updated: 2026-02-02 Confidence: High

Summary

Full user acceptance testing of Phase 6 (The Mesh — Distributed Writes). All 67 Phase 6 tests pass, existing functionality verified, new cluster node binary works correctly. Two minor issues found and fixed during testing.

Key Facts:

All Phase 6 crates tested: merkle (16), rpc (5), sync (10), cluster (28), battery11 (8)
New stemedb-node binary demonstrates cluster routing
Go SDK examples (basic, conflict, skeptic) all pass
Single-node API and Swagger UI verified working
