Fixed DAG-level `on_failure_callback` never firing with KubernetesExecutor. The `DagRunContext` validator only caught `DetachedInstanceError` when accessing ORM relationships, but other SQLAlchemy exceptions (e.g. `InvalidRequestError`) crashed `produce_dag_callback` silently — no callback was produced and no log was emitted. - Broadened exception handling in `DagRunContext` validator to catch all exceptions - Made `produce_dag_callback` resilient: sends callback with minimal context on `DagRunContext` failure instead of losing it entirely - Added warning log when DAG processor skips callbacks with mismatched `bundle_name` - Added info log when scheduler sends a callback to the DAG processor closes: #63374 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Opus 4.6) Generated-by: Claude Code (Opus 4.6) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
