AIngle v0.6.3 — Total data integrity hardening

18 bugs fixed across the entire data pipeline. Zero data loss on crash,
zero panics from lock poisoning, zero silent write failures.

- Persistent ProofStore with Sled backend (was in-memory only)
- Proofs included in Raft cluster snapshots
- Periodic auto-flush every 300s (--flush-interval)
- Audit log fsync + error reporting
- Atomic batch insert via sled::Batch
- P2P DAG action sync via tip exchange
- Sled lock contention fix (separate proofs.sled)

- DAG signing key, Kaneru agent state, Ineru snapshot,
  P2P node key, peer store — all now fsync after write

- WAL writer, rule engine, Kaneru agent, P2P REST,
  ProofStore init — no more unwrap/expect in production paths

- POST /api/v1/triples/batch — atomic bulk insert endpoint
- --flush-interval CLI flag
- Proof verify returns 200+valid:false instead of 422

- 8 new cross-subsystem data integrity tests
- 1747+ tests passing, 0 regressions
- 45 files changed, 1816 insertions, 154 deletions
