Scheduler double counts Failed status of dag_run in case when dagrun_timeout was specified.

### Apache Airflow version Other Airflow 2 version (please specify below) ### If "Other Airflow 2 version" selected, which one? 2.9.3, 2.10.5 ### What happened? I am using Airflow 2.9.3 with a listener plugin to track dag_run status, similar to the example in the official documentation: https://airflow.apache.org/docs/apache-airflow/2.9.3/howto/listener-plugin.html. I noticed that when a dag_run times out, the Failed status is triggered twice instead of once. The run_id gets a Failed status the first time when the dagrun_timeout is hit and then a second time a little while later. A similar issue appears to occur in version 2.10.5. Here you can see run_id repeats and have different duration: <img width="841" height="143" alt="Image" src="https://github.com/user-attachments/assets/08993e8b-40c4-4af6-8130-73608cee8867" /> ### What you think should happen instead? Status Failed of DagRun should be emitted only once when dagrun timed-out. ### How to reproduce Here is DAG that I use to reproduce issue: ```python from datetime import timedelta from airflow import DAG from airflow.operators.bash_operator import BashOperator from airflow.utils.dates import days_ago default_args = { 'owner': 'airflow', 'depends_on_past': False, 'start_date': days_ago(1), 'schedule_interval': '@daily', 'email': ['airflow@example.com'], 'email_on_failure': False, 'email_on_retry': False, 'retries': 0, 'retry_delay': timedelta(minutes=5), } dag = DAG( 'mydag-fail-1', default_args=default_args, description='A simple tutorial DAG', schedule_interval=timedelta(minutes=5), dagrun_timeout=timedelta(seconds=20), max_active_runs=1 ) t1 = BashOperator( task_id='echo_sth', bash_command='echo sth', dag=dag, ) t2 = BashOperator( task_id='sleeping_task', depends_on_past=False, bash_command='sleep 30', dag=dag, ) t1 >> t2 ``` Code of my plugin: plugun.py ```python from airflow.plugins_manager import AirflowPlugin from da…
