Add test_submit_first integration test and JobInfo dataclass

[Copilot]

The submit first command (multi-cluster "first to start wins" submission) had no integration test coverage, unlike the single-cluster submit path. Additionally, submit() previously returned a bare int | None, making it impossible to tell which cluster won when using cluster="first".

Changes

• cluv/cli/submit.py: Adds a frozen JobInfo dataclass with cluster: str, job_id: int, and submit_time: datetime fields. Refactors submit() and submit_first() to return JobInfo | None instead of int | None. The submit_time is captured using datetime.now(timezone.utc) right after sbatch completes.

• tests/test_integration.py: Adds test_submit_first which calls submit(cluster="first", ...) against all available SUBMIT_SUPPORTED_CLUSTERS

  • Skips gracefully if no supported cluster has an active SSH connection
  • Asserts the returned value is a JobInfo instance
  • Cancels the winning job in a finally block
  • Updates test_submit to assert on JobInfo and verify job_info.cluster

job_info = await submit(
    cluster="first",
    job_script=Path("scripts/safe_job.sh"),
    sbatch_args=["--time=00:00:30"],
    program_args=["python", "--version"],
)
assert isinstance(job_info, JobInfo)

Timeout is 300 s (vs. 180 s for test_submit) to account for syncing across multiple clusters before submission.

@copilot refactor the submit function so that it returns a new JobInfo (frozen) dataclass, with the cluster: str, job_id: int, submit_time: datetime fields.

Note, otherwise, we can't tell from the output on which cluster is was run when cluster is first.

Update the PR to also mention this change.

Done in commit 0442db6. Added a frozen JobInfo dataclass with cluster: str, job_id: int, and submit_time: datetime fields. Both submit() and submit_first() now return JobInfo | None. The submit_time is captured using datetime.now(timezone.utc) right after sbatch completes (not when submit_first returns), so it reflects actual submission time. Both test_submit and test_submit_first are updated to assert on JobInfo and check job_info.cluster.

Pull request overview

This PR improves the cluv submit API to return structured metadata about a submission (including the winning cluster for cluster="first") and adds integration coverage for the multi-cluster “first to start wins” submit path.

Changes:

• Introduces a frozen JobInfo dataclass and updates submit() / submit_first() to return JobInfo | None instead of int | None.
• Adds a new integration test test_submit_first and updates test_submit assertions to work with JobInfo.
• Records a UTC submission timestamp at submit completion time.

@copilot Fix pre-commit issues

Fixed in commit 1804308. The applied review suggestion had introduced a malformed next() call (missing closing ) and using wrong variable r). Corrected to next((r for r in remotes if r.hostname == job_info.cluster), None) — all ruff checks now pass.
