[PR] skip: Skip stuck-in-queued reschedule when the queue attempt already started [airflow]
ashutosh264 opened a new pull request, #68820:
URL: https://github.com/apache/airflow/pull/68820
When the scheduler's stuck-in-queued handler runs, it can still reschedule a task instance whose worker has already picked it up. That race shows up with deferrable operators: a task moves through queued → running → deferred, but a stale queued row with an expired queued_dttm gets reset to scheduled and can resume or succeed too early.
This change refreshes each candidate task instance before handling it, and skips stuck-in-queued reschedule when the state is no longer queued, or when a running log entry exists for the current try at or after the current queued_dttm.
Closes: #65248
Test plan (in case reviewers need it):
`uv run --project airflow-core pytest airflow-core/tests/unit/jobs/test_scheduler_job.py::TestSchedulerJob::test_handle_stuck_queued_skips_when_queue_attempt_started -xvs`

Fixed newsfragment to match PR number, which was introduced as I was working on one more issue.
This was only a check which failed.

Congratulations on your first Pull Request and welcome to the Apache Airflow community! If you have any issues or are unsure about any anything please check our [Contributors' Guide](https://github.com/apache/airflow/blob/main/contributing-docs/README.rst)
Here are some useful points:
- Pay attention to the quality of your code (ruff, mypy and type annotations). Our [prek-hooks]( https://github.com/apache/airflow/blob/main/contributing-docs/08_static_code_checks.rst#prerequisites-for-prek-hooks) will help you with that.
- In case of a new feature add useful documentation (in docstrings or in `docs/` directory). Adding a new operator? Check this short [guide](https://github.com/apache/airflow/blob/main/airflow-core/docs/howto/custom-operator.rst) Consider adding an example Dag that shows how users should use it.
- Consider using [Breeze environment](https://github.com/apache/airflow/blob/main/dev/breeze/doc/README.rst) for testing locally, it's a heavy docker but it ships with a working Airflow and a lot of integrations.
- Be patient and persistent. It might take some time to get a review or get the final approval from Committers.
- Please follow [ASF Code of Conduct](https://www.apache.org/foundation/policies/conduct) for all communication including (but not limited to) comments on Pull Requests, Mailing list and Slack.
- Be sure to read the [Airflow Coding style]( https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#coding-style-and-best-practices).
- Always keep your Pull Requests rebased, otherwise your build might fail due to changes not related to your commits.
Apache Airflow is a community-driven project and together we are making it better 🚀.
