fix(runtime): keep renewing the lease while a staged terminal run finalizes (#6263 )

* fix(runtime): keep renewing the lease while a staged terminal run finalizes

With an event store, run_agent stages the terminal status in memory and
commits it to the run store only after the journal flush, delivery receipt,
workspace scan and duration checkpoint. _renew_leases selected runs by local
status, so it stopped renewing as soon as the status was staged. A
finalization longer than lease_seconds + grace_seconds let a peer, or this
worker's own reconciler, claim the still-active row and record the
successful run as an orphan error.

The worker now marks RunRecord.terminal_commit_pending until the deferred
commit is attempted, and lease renewal treats it like the existing
scheduled-goal barrier: keep renewing, release on a confirmed own commit,
and fence when a peer claims the row. A fenced run stops renewing.

* docs(changelog): reference #6263 for the staged terminal lease renewal fix
