feat(ha-commit-engine): per-LSN majority commit engine core (task 1.2)
commit_on_ack: active-standby (non-catch-up, connected) watermark scan,
descending sort, candidate arr[n_peers/2-1], clamped to appended log,
monotonic single-site committed_lsn store, condvar broadcast, never
blocks beyond engine mutex. RETAIN returns immediately. Self-quorum for
n_peers<=1; zero-fill makes zero-standby commit impossible. 7/7 task-1.1
tests green unmodified; full suite at known 3-failure baseline.

test(ha-commit-engine): RED tests for per-LSN majority evaluation (task 1.1)
commit.h umbrella-verbatim interface + inert stub commit.c (test target
only); 7 Unity tests covering per-LSN vs acked_lsn>0 counting, majority
median, monotonicity, append clamp, lagging standby, RETAIN immediacy.
All 7 fail RED as intended. Documented 3 pre-existing masked suite
failures (bug-411) and the per-group exit-code masking root cause.

chore: baseline snapshot — prior-session work + ha-consistency-invariants spec family
Pre-existing uncommitted work: ha-repl-hardening payload data plane (7.x),
heartbeat liveness fix (Req 1.3), connection-reuse ASAN fixes, doc cleanup.
New: ha-consistency-invariants umbrella (requirements/design/research) and
its four implementation sub-specs (specs generated via batch, cross-spec
review applied), steering roadmap + product.md Raft+CP decision.
