rock 41cdff3676 feat(rbac): wire AccessGuard into HTTP server and retrieval pipeline

HTTP Layer Integration:
- Add access_guard to AppState with builtin_role_provider
- Add to_rbac_claims() to convert JwtClaims → RBAC Claims
- Add query_result_to_resource_meta() for result filtering

Query Handler (/memory/query):
- RBAC filter applied after M3.8 optimization
- Batch check_access for all results
- Log filtered count per request

Context Handler (/memory/context):
- Project-level access check before lookup
- Return 403 if user lacks project access

Code Cleanup:
- Move http_server from bin to lib module
- Use mem_cli::http_server in main.rs

All 660+ tests passing.

Architecture Decisions Made

Decision	Rationale
Trait-based design	Pluggable: swap scorers/providers without code changes
Decorator pattern	Composition over inheritance (MetadataBoostingScorer)
ScoringPipeline	Unifies all scoring variants (global, project, semantic)
PolicyProvider trait	Support Vault/Postgres/Redis transparently
AccessChecker composition	Split fat method into 3 single-purpose checkers
Test fixtures builders	DRY: reusable OidcClaimsBuilder, AccessPolicyBuilder
MockPolicyProvider	Fast, no-I/O testing without Vault dependency

Next Steps (Priority Order)

Immediate (Today/Tomorrow)

Production Backend Integration
- Connect FullPipeline to pgvector
- Connect FullPipeline to OpenSearch
- Real embedding generation

Near-term (This week)

Performance Benchmarking
- Create homelab vault structure (test data)
- Benchmark retrieval latency (target < 500ms)
- Benchmark LLM call reduction (target 70-80%)
- Benchmark chunk accuracy (target NDCG > 0.85)
Production Integration
- Connect to pgvector for semantic search
- Connect to OpenSearch for lexical search
- Verify hybrid search accuracy

Later (Next week+)

Full Integration Testing
- End-to-end scenarios: agent query → wiki-scoped search → RBAC filtering → LLM
- Test failures (auth denied, policy mismatch, etc.)
- Test graceful degradation (Obsidian unreachable, cache miss, etc.)

Known Limitations (To Address)

ScoringPipeline: placeholder for semantic/pgvector (not yet connected)
VaultPolicyProvider: doesn't reload on file change (hot-reload TBD)
AccessDecisionEngine: no timeout on checker execution (TBD)
Test fixtures: MockPolicyProvider uses sync Mutex (should be Arc)
No benchmarks yet: latency/throughput targets TBD

How to Run Tests
