Add TLA+ formal verification specs for backup and recovery
...
- backup.tla: models backup/restore/verify/cleanup with properties:
BackupSnapshotsValid, RestoreIntegrity, VerifyIntegrity,
RetentionInvariant, HistoryConsistency, BackupIdValid
- recovery.tla: models WAL replay REDO/UNDO with properties:
RedoCommitted, RecoveryCompleteness, WalIntegrity
- Added models/backup.cfg and models/recovery.cfg with bounded constants
- Updated run_all.sh to include both new specs
- All 9 TLA+ specs pass TLC model checking

...
Added 3 new TLA+ specs:
- gossip.tla — SWIM gossip membership & failure detection
- deadlock.tla — wait-for graph deadlock detection
- sharding.tla — consistent hashing shard assignment
Improved existing 4 specs:

ParticipantStateValid; increased to MaxTxnId=3
- mvcc.tla: added CommittedMustStart, CommittedVersionsUnique
- replication.tla: added AppliedLteCurrent, SemiSyncQuorum
Infrastructure:

- CHANGELOG.md
- ANALYSIS.md (weak spots & improvement plan)
- run_all.sh script for batch TLC verification
- CI verify job in GitHub Actions
- Updated README with new specs and properties
Total: 7 specs, 26 invariants, 11.6M states checked, 0 errors
