feat: Concept hierarchy (Phase 5D) - ConceptPath, source schemes, AliasStore

Implements hierarchical subject identifiers with scheme-based source tier inference:

- ConceptPath type with parse/wire_format, leaf/parent, prefix matching
- SourceScheme registry mapping schemes to default SourceClass tiers:
  - rfc://, fda://, ietf:// → Regulatory (Tier 0)
  - peer://, pubmed:// → PeerReviewed (Tier 1)
  - code://, wiki:// → Expert (Tier 3)
  - blog://, anon:// → Anecdotal (Tier 5)
- AliasStore for cross-scheme entity resolution (bidirectional indexing)
- API endpoints for concept operations
- Battery tests 8, 9 & 10 for concepts, aliases, and advanced signatures
- Go SDK updates for concept types and signing

Completes Phase 5, advancing to Phase 6 (Distributed Writes).

feat: Index persistence (Phase 5C) - vector hot/cold, visual checkpoint

Phase 5C (Index Persistence) implementation:
- PersistentVectorIndex with hot/cold architecture
  - Hot: in-memory HNSW for recent vectors
  - Cold: memory-mapped HNSW loaded from disk
  - Background builder for WAL replay and atomic swap
  - BLAKE3 integrity verification
- PersistentVisualIndex with checkpoint persistence
  - BkTreeSnapshot with rkyv serialization
  - CRC32C corruption detection
  - Atomic write pattern (temp → fsync → rename)
- Key codec additions for vector index metadata
- Split large files into modules (<500 lines each)
  - battery_pre_sentinel.rs → battery/ directory
  - visual_index.rs → visual_index/ directory
  - persistent.rs → persistent/ directory
- Refactored ingest worker tests for clarity
- Updated roadmap to mark Phase 5 complete
