* fix: honest publish_review reporting + structured thread-not-found errors
- Document skipped_empty_re_review and dry_run in the publish_review
docstring and add a closing-summary contract to the reviewer prompt so
the agent never claims a review was published when review_id is null.
- Raise ReviewerThreadMissingError from replace_findings on SDK
NotFoundError; add_finding/update_finding/publish_review return a
structured do-not-retry result instead of raising, so the agent reports
the blocker after one failure instead of retrying 10-30 times.
* fix: translate thread 404s across all reviewer tool boundaries
get_thread_metadata now raises ReviewerThreadMissingError instead of
swallowing a missing thread as {} (which produced misleading 'No finding
found' results), set_reviewer_thread_metadata translates the SDK 404 the
same way, and every reviewer tool entrypoint (add/update/list findings,
publish_review incl. eval dry-run, resolve/reply thread) returns the
structured do-not-retry result.
