Concurrent CI or review webhooks can try to remove the same PR label. The second deletion returns 404 "Label does not exist", aborting the webhook with HTTP 500 and generating Sentry errors.
Treat that specific response as successful cleanup and log it at INFO, while preserving other API errors. Add regression coverage for concurrent check runs, stale stage labels, continued cleanup, and logging.
Validation: all 206 tests pass; all pre-commit checks pass.
