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.) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
