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
