efe621c124 feat(ha-term-safety): retire term-0 repl_broadcast live send; carry leader term on replication (task 3.4) 
Closes bug-990: the live replicator repl_broadcast wire-encoded term=0
(entry.term was never set), so standbys persisted hdr.term=0 and took the
legacy direct-apply path instead of the library (term,lsn) intake. Now the
live broadcast and catch-up streamer carry the leader's real term + AE prev
tuple; ha_apply_wal_catchup_entry routes every term-carrying entry through
raft_on_append_entries_request -> on_persist_entry (leader term stamped),
retiring the term-0 direct-apply. Standbys now persist the leader's real term
and reconcile by (term,lsn); the live commit chain is end-to-end.

848/849/850 + persist-before-ACK + commit-barrier + bug-960 preserved.
Proven at integration level; the definitive live STRICT_TERM failover run is
env-blocked here (bug-924 overlayfs) and recommended on a real fs.

9cdeba5816 test(ha-commit-barrier-rollout): RED tests for config barrier (task 5.1) 
6 RED carriers pinning the three configAck defects (previous-tag acks
count, n_active==0 success shortcut, no-self-count denominator) and the
push/upgrade failure path (logged-only result, unconditional success
ACK + restart). 2 sanctioned pins (single-member, success-unchanged).
Behavior-preserving signature change: push_config_to_standbys gains
acked_out (return still legacy push count; 7 call sites NULL'd,
body-diff verified). 29/6 in group; no collateral failures.

d1353360cc test(ha-commit-engine): RED integration tests for ACK feed and sync-append (task 5.1) 
Tests 30-34: wired repl_on_ack feeds engine, membership mutators
trigger re-evaluation, per-entry sync-append contract (stale-ACK
rejection, committed_lsn unmoved on timeout, n_peers=1 replaces
-ENODEV). test_repl_majority walAck cases rewired to per-LSN
semantics (configAck byte-identical). Sanctioned scaffolding:
entry_lsn param on repl_wait_majority_ack (legacy body byte-identical,
callers pass 0), inert repl_set_commit_engine stub. 9 RED failures;
baseline signatures unchanged. LSN-0 edge documented for 5.2/5.3.
