New files:
- observe.go: RegistryStatus, SenderStatus, RecoveryLog for debugging
- integration_test.go: V2-boundary integration tests through real
  engine entry path

Observability:
- Registry.Status() returns full snapshot: per-sender state, session
  snapshots, counts by category (InSync, Recovering, Rebuilding)
- RecoveryLog: append-only event log for recovery lifecycle debugging

Integration tests (6):
- ChangedAddress_FullFlow: initial recovery → address change →
  sender preserved → new session → recovery with proof
- NeedsRebuild_ThenRebuildAssignment: catch-up fails → NeedsRebuild
  → rebuild assignment → history-driven source → InSync
- EpochBump_DuringRecovery: mid-recovery epoch bump → old session
  rejected → new assignment at new epoch → InSync
- MultiReplica_MixedOutcomes: 3 replicas, 3 outcomes via
  RetainedHistory proofs, registry status verified
- RegistryStatus_Snapshot: observability snapshot structure
- RecoveryLog: event recording and filtering

Engine module at 54 tests (12 + 18 + 18 + 6).
