feat(ha-commit-engine): WAIT mode, admission cap, writable_lsn gate (task 2.2)

Browse source 
commit_submit(WAIT): n_vcpus-relative admission cap with fast retriable
NOT_READY (admission-cap-only per corrected contract), CLOCK_REALTIME
timedwait loop on the per-LSN + gate predicate, post-timeout predicate
re-check, n_peers<=1 self-quorum through the single advancement site.
Inflight counter accurate under engine lock for the full blocking
interval with XCE_TESTING asserts. 16/16 group tests green unmodified;
full suite at the 3-failure baseline.
