pingqiu 20d70f9fb6 feat: add V2 engine replication core (Phase 05 Slice 1)

Creates sw-block/engine/replication/ — the real V2 engine ownership core,
promoted from sw-block/prototype/enginev2/ with all accepted invariants.

Files:
- types.go: Endpoint, ReplicaState, SessionKind, SessionPhase, FSM transitions
- sender.go: per-replica Sender with full execution + rebuild APIs
- session.go: Session with identity, phases, frozen target, truncation, budget
- registry.go: Registry with reconcile + assignment intent + epoch invalidation
- budget.go: CatchUpBudget (duration, entries, stall detection)
- rebuild.go: RebuildState FSM (snapshot+tail vs full base)
- outcome.go: HandshakeResult + ClassifyRecoveryOutcome

Tests (ownership_test.go, 13 tests):
- Changed-address invalidation (A10)
- Stale session ID rejected at all APIs (A3)
- Stale completion after supersede (A3)
- Epoch bump invalidates all sessions (A3)
- Stale assignment epoch rejected
- Rebuild exclusivity (catch-up APIs rejected)
- Rebuild full lifecycle
- Frozen target rejects chase (A5)
- Budget violation escalates (A5)
- E2E: 3 replicas, 3 outcomes
