Operator preference: each !testme should get its own comment response so a
re-run is visible in the PR timeline. process_testme now always posts a fresh
⏳ placeholder comment; watch_and_reflect edits THAT comment to the result.
(Was: reuse/edit a single marker comment in place — which made re-runs on an
unchanged head invisible, only updating commit status.)
