feat(ha-repl-hardening): per-standby convergence tracking from heartbeats (task 3.1)

Browse source 
ha_process_standby_state stores (tag, lsn) per standby, evaluates
convergence (tag>=committed && lsn>=committed), sets converged flag,
logs INFO only on transition. Wired into repl_ack_decode_and_dispatch.
5 tests: converged, lsn-behind, tag-behind, regression, multi-peer.

- [ ] 3. Primary-side: Unified heartbeat-driven replication decision loop
- [ ] 3.1 Implement per-standby convergence tracking update
- [x] 3.1 Implement per-standby convergence tracking update
- On each heartbeat reply from a standby, extract `appliedLsn` and `configTag` from `stateReport`
- Store in `standby_reported_tag[idx]` and `standby_reported_lsn[idx]`
- Evaluate convergence: `reported_tag >= committed_tag AND reported_lsn >= committed_lsn`
