Renn F a3d1769018 [F127] per-task advisory lock prevents open_pr milestone double-emit
open_pr's idempotent re-entry guard (pr_number is not None) read t.pr_number
from an unlocked fetch. Two concurrent same-task open_pr calls (the
alive-but-unresponsive respawn race) both fetched pr_number=None, both passed
the guard, both ran the runner (GitHub 422 ensures one PR), and both reached
_record_milestone_progress -> a double-emitted 70% 'opened PR #N' entry.

Fix: acquire_task_lock (pg_advisory_xact_lock, seed 2) before the fetch, held
through the runner + milestone + request commit. The second concurrent call
blocks until the first commits, then its fetch sees the committed pr_number
and the idempotent guard short-circuits without re-emitting. Per-task (single-
active-task guard means same-task concurrent open_pr is only the bug case).
