- Reject follower writes if any statement in the batch is DML/COMMIT
(not only stmts[0]).
- COMMIT always emits empty-valued kvPairs for isDelete entries.
- applyCommand updates LSM plus secondary B-tree/FTS/HNSW indexes
(applyReplicatedPut/Delete) so follower index scans see replicated rows.
- Tests: not-leader append, commit timeout, index apply unit, E2E
index-backed SELECT on follower.
- Fix runTcpServer to run the already-wired Server (raftNode was assigned
on a different instance that never accepted clients).
- Cap raft peer connect at 200ms and fan out heartbeats in parallel so a
dead peer cannot stall AppendEntries to the live majority.
- Add raft_writes_e2e_test: 3-node write replication, follower rejection,
and post-failover writes; wire into nimble test + gitignore.
