release: bump all crates to v0.6.3 — total bug purge across data pipeline

This release fixes 16 bugs found during an exhaustive input/output
audit of the entire AIngle data pipeline:

## Data integrity (6 fixes)
- Persistent ProofStore with Sled backend (was in-memory only)
- Proofs included in Raft cluster snapshots (new nodes got 0 proofs)
- Periodic auto-flush every 300s (crash = data loss window reduced)
- Audit log fsync + error reporting (was silently dropping writes)
- Atomic batch insert via sled::Batch (partial writes impossible)
- P2P DAG action sync via tip exchange (DAG wasn't replicated)

## fsync hardening (5 fixes)
- DAG signing key write — error handling + fsync
- Kaneru agent state + ML weights — fsync after save
- Ineru memory snapshot — fsync after write
- P2P node identity key — fsync on all platforms
- Peer store JSON — fsync after write

## Panic elimination (5 fixes)
- WAL writer: lock().unwrap() → lock().map_err() (4 sites)
- Rule engine: poisoned lock recovery (9 sites)
- Kaneru agent: unwrap on Option → graceful early return
- P2P REST endpoints: unwrap → HTTP 500 error response
- ProofStore init: blocking_write removed entirely

## Testing
- 8 new cross-subsystem data integrity tests
- 1092+ tests passing across all core crates, 0
