- [ ] 2. Standby-side: Wire WAL catch-up and heartbeat state reporting
- [ ] 2.1 (P) Wire `OPCode_walCatchupEntry` single-entry handler on standby
- [x] 2.1 (P) Wire `OPCode_walCatchupEntry` single-entry handler on standby
- Replace the stub in the dispatch switch (returns 0) with a call to `apply_wal_entry()` for single entries
- On success, advance `applied_lsn` atomically; on error, log ERROR and skip — do not crash
- Standby remains in `CTRL_STANDBY` throughout; does not accept job dispatch during catch-up
