   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`
