* fix(job): honor custom retry in job.result()

The `_AsyncJob.result()` method was not correctly passing the `retry`
argument to the superclass's `result()` method when the `retry` object
was the same as the default retry object. This caused the default
retry settings to be ignored in some cases.

This change modifies the `result()` method to always pass the `retry`
argument to the superclass, ensuring that the provided retry settings
are always honored.

A new test case is added to verify that `job.result()` correctly
handles both the default retry and a custom retry object.

* Update tests/unit/test_job_retry.py

* Update tests/unit/test_job_retry.py

* blacken and lint

* udpates retry handling and testing of retry handling

* Update tests/unit/test_job_retry.py

* feat: Add ExternalRuntimeOptions to BigQuery routine

This change introduces the `ExternalRuntimeOptions` class to the
`google.cloud.bigquery.routine` module, allowing users to configure
runtime options for external routines.

Key changes:
- Created the `ExternalRuntimeOptions` class with setters and getters for
  `container_memory`, `container_cpu`, `runtime_connection`,
  `max_batching_rows`, and `runtime_version`.
- Updated the `Routine` class to include an `external_runtime_options`
  property that accepts an `ExternalRuntimeOptions` object.
- Added comprehensive unit tests for the new class and its integration
  with the `Routine` class, including tests for both valid and invalid
  input values.

This PR updates the librarian sha to support v1.0.0

…e with pyarrow (#2338)

Due to an issue with `pyarrow`, a significant dependency for certain
python-bigquery use cases, not being compatible with Python 3.14, we
temporarily skipped the failing CI/CD check for 3.14 while awaiting the
update to pyarrow. Pyarrow is now fully compatible, so that filter is
being removed.

**KNOWN ISSUES**: this will show that unittests for 3.14 are failing.
This has nothing to do with this PR/these changes. It is being addressed
in an alternate mod. It is due to a missing dependency related to
handling IO for `geopandas` (namely it is missing `libgdal-dev`, etc
which are normally installed with `pyogrio` + `geopandas`). Because
`pyogrio` is currently not compatible with Python 3.14 the tests in 3.14
cannot complete.

This should not prevent **this PR from being merged** to help solve the
current issue, which is a blocker for getting our continuous tests to
green.

This PR effectively moves ownership for this repo to the python language
team, and removes api-bigquery as the defacto code owner.

PR created by the Librarian CLI to initialize a release. Merging this PR
will auto trigger a release.
