feat(homecore-recorder/p1): ADR-132 SQLite recorder + fnv64a attr dedup (14 tests pass)

- SQLite-backed state history with HA-compat schema (states, state_attributes,
  events, recorder_runs) mirroring recorder schema v48
- FNV-1a 64-bit attribute deduplication matching HA's db_schema.py fnv64a
- RecorderListener subscribes to StateMachine broadcast and persists every
  state change; subscription created at construction to avoid missed events
- SemanticIndex trait + NullSemanticIndex for P1; ruvector-backed impl stub
  feature-gated behind --features ruvector for P2 hand-off
