Add record_job_reconcile_pending_fact(cluster_t*, job_t*) to job.c:
eagerly applies apply_job_update_transition(job, JOB_STAT_PEND) (real,
live mutation, not a deferred peek -- matching dispatch_a_job_'s
established pattern, not record_job_finish_fact's), releases
job->job.allocs on an applied (non-no-op) transition, then durably
appends via the generic persist_submit_job_fact(WAL_JOB_UPDATE). Caller
holds job's lock throughout and is responsible for calling
persist_notify_job_updated_already_persisted() after unlocking -- this
function deliberately does not call it itself.
Closes bug-1631 at this new call site: a RUN job with a real allocation
reconciled to PEND (Requirement 4.6, worker reports it unrecognized)
would otherwise carry a stale allocation into its next dispatch attempt,
exactly the gap bug-1631 documented as dormant until something re-admits
an already-dispatched job to the scheduler's PEND pool -- this feature
is that path. dispatch_a_job_ itself is unchanged (still correct for a
job's first-ever dispatch, the only case reachable there).
3 tests: allocs release + eager-mutation-before-unlock proof, no-op on
already-pending, and the Requirement 4.4 terminal-state-preservation
proof (rejects overwriting JOB_STAT_DONE).
