Worker-rejoin-resync sets XCE_WORKER_RECONCILING and pushes it to the
scheduler, which correctly freezes that worker's resInUse mid-reconciliation
(bug-1799/1801). But resync_resolve_round() only cleared the bit on the
controller's own worker_t, never notifying the scheduler -- so once a
rejoin round resolved, the scheduler's copy stayed RECONCILING forever,
permanently freezing that worker's resource accounting even after every
job on it finished. Live-observed via a replay capture: a 22-slot worker
stuck at used=22.00 for the rest of the run with zero RUN jobs left.
Added persist_notify_worker_status_updated() (mirrors bug-1679's job-side
persist_notify_job_updated_already_persisted()) and call it from
resync_resolve_round() so HOOK_DETAIL_WORKER_UPDATE fires without a
spurious WAL append. TDD: new spy-hook regression test, RED confirmed
against the unfixed code, GREEN after the fix. Full controller_unit_test
suite: 1220 Tests, 0 Failures, 0 Ignored.
