## Why
On Airflow versions before 3.3, an `OSError` while reading the Object
Storage durable journal was treated as though the journal did not exist.
That could cause the task to issue a new LLM request and repeat external
tool side effects, even though a previous attempt may already have completed
them.
## What
- Keep treating a missing journal as a normal first execution.
- Log and propagate an `OSError` when an existing journal cannot be read.
- Stop the current task before it can re-execute LLM or tool steps. Airflow
may retry according to the task's configured retry policy; once storage is
available again, the existing journal can be replayed.
- Let Airflow retry according to the task's configured retry policy; once
storage is available again, the existing journal can be replayed.
- Add a regression test for an Object Storage read failure.
