fix: reviewer publishes against stale head_sha on mid-run re-review (#1393) 
* fix: resolve reviewer head_sha from thread metadata, not frozen run config

A push that lands while a reviewer run is in flight is delivered as a
queued message into that run. The run's configurable is frozen at
creation, so its head_sha still names the commit the run was created for
— not the commit just pushed. publish_review then anchored the GitHub
review to the stale commit and regressed last_reviewed_sha to it, and
add_finding/update_finding stamped findings with the stale SHA.

Persist the current head in thread metadata at every reviewer dispatch
(both the ready-for-review and push paths, before they branch to create
a run or queue a message), and add resolve_review_head_sha() which
prefers the metadata head over the run config. Wire it into
publish_review (review commit_id + last_reviewed_sha), add_finding
(first_seen_sha) and update_finding (last_confirmed_sha). Falls back to
the run config when metadata carries no head (first review, eval, tests).

* fix: persist head_sha in manual review dispatch (trigger_pr_review_from_ref)

resolve_review_head_sha prefers metadata[head_sha] over the run config,
and the push/ready dispatchers write it — but trigger_pr_review_from_ref
(Slack/GitHub @open-swe review, request_pr_review tool) created a run
with a freshly-fetched config head while leaving metadata's head stale
from a prior dispatch. A manual re-review at a newer commit would then
resolve to the old head and publish/advance findings against it.

Persist head_sha in that dispatch's metadata write too, so every
run-creating reviewer dispatch keeps metadata in sync with the head its
run targets. Caught by the Open SWE reviewer on this PR.
