test(ha-commit-engine): membership re-evaluation regression tests (tasks 3.1+3.2 joint)

Browse source 
Tests 17-20: catch-up ACK exclusion vs pending waiter, membership-change
wake of covered waiter, removal-below-majority fails at own deadline
(no forced early-fail), non-blocking bound. Landed GREEN: task 1.2's
commit_on_membership_change already implements the full 3.2 contract,
so RED was unachievable; reviewer confirmed mutation-killing power and
zero production changes. 20/20 group tests; suite at baseline.

- repl_add_standby returns the SLOT INDEX (>=0) on success, not 0 (2026-06-11, ha-commit-engine task 1.1): asserting `== 0` breaks on the second standby. Assert `>= 0` or the expected index.
- Unity harness quirks in controller_unit_test (2026-06-11): (a) failure lines misattribute the FILE — Unity.TestFile comes from whichever group's UNITY_BEGIN ran, so a failure printed as test_repl_unit.c:294 may live in test_p2_integration.c; locate the actual test by grepping for the test NAME. (b) Each group's UNITY_BEGIN resets counters, so the process exit code only reflects the LAST group — failures in earlier groups are masked (exit=0); meson reports green despite real failures. Grep output for FAIL with `grep FAIL` on the raw log (ANSI codes sit between ':' and 'FAIL', so `grep ":FAIL"` misses them).
- 3 pre-existing controller suite failures on persistent_ha baseline (2026-06-11, verified by stash/rebuild without ha-commit-engine changes, see bug-411): test_committed_lsn_does_not_advance_on_timeout (rc -110 vs expected 0 — persist_wal_sync_append now returns -ETIMEDOUT, test expects old rc==0+sync_rc contract), test_repl_ack_after_promote_gate_allows_jobsub and test_rdhup_primary_dispatch_gate_opens (both -10013: ha_has_write_quorum false, standby_endpoints empty with n_peers=2).
- ha-commit-engine: task 1.2 shipped commit_on_membership_change as a FULL re-evaluation (commit_advance_locked + cond broadcast), and majority_candidate_locked already excludes in_catch_up + ep==NULL slots. Task 3.1 membership tests are green-on-arrival; task 3.2 is a no-op (verified 2026-06-11, tests 17-20 in test_commit_engine.c).
