feat(worker-rejoin-resync): apply reported outcomes idempotently (task 3.2)

Browse source 
Add resync_apply_report()/resync_apply_running_entry()/
resync_apply_finished_entry()/resync_apply_unrecognized_entry() to
resync.c: routes each entry in a worker's job-state report to the
correct existing idempotent path (still-running -> clear from outstanding
set, no fact; finished-success/failure -> record_job_finish_fact_at/
on_job_fail; unrecognized -> record_job_reconcile_pending_fact;
unqueried extra -> record_job_reconcile_assign_fact or no-op), discards
reports for superseded rounds (Req 6.1/6.3), and resolves the round once
its outstanding set empties.

Also fixes bug-1747 (Req 4.2): adds record_job_finish_fact_at(),
additive alongside the unmodified record_job_finish_fact, so a
finished-success reconciliation entry records the WORKER-reported
finish time instead of reconciliation-processing time -- proven via a
real WAL-write + persist_recover() restart-replay test. The FAIL-side
half of the same gap (WAL_JOB_FAIL carries no fail-time wire slot at
all, for any caller) is confirmed pre-existing and systemic, correctly
left out of this task's scope.

Three review rounds surfaced and fixed two real, distinct bugs in the
unqueried-extra-job routing guard (see tasks.md's Implementation Notes
for the full account and the general lesson about re-deriving a full
truth table after a partial boolean-guard fix): round 1 caught the
wrong axis (terminal-vs-non-terminal instead of assignment-status,
Req 4.8); round 2 caught that the first fix's short-circuit clobbered
an already-terminal job's DONE/EXIT back to RUN (Req 4.4), including
confirming the implementer's own test had certified the bug as correct;
round 3 independently re-derived the final three-way guard from scratch
and found no further defect. bug-1748 logged for the guard fix.

Full controller suite: 1239 tests, 0 failures.
