test(ray): give conda-env UDF actor startup more headroom

[rohitkulshreshtha]

What

test_udf_with_conda_inject_dependencies builds a fresh conda env and pip-installs daft at actor startup. On shared/loaded CI runners that can exceed the default 120s actor_udf_ready_timeout, so the test intermittently fails with UDF actors failed to start within 120 seconds instead of the expected No module named 'faker' — a flake unrelated to the code under test.

Change

Scope actor_udf_ready_timeout to 300s for this one test via daft.execution_config_ctx(...), giving the conda env build headroom. Behavior-only timeout bump — no production code change, and the context manager restores config afterward so other tests are unaffected.

Greptile Summary

This PR wraps the entire body of test_udf_with_conda_inject_dependencies in a daft.execution_config_ctx(actor_udf_ready_timeout=300) context manager to give CI runners extra time (300 s vs. the 120 s default) for fresh conda env creation before concluding the test has failed.

• Scopes the higher timeout to only this one test via the context manager, so no other tests are affected and production config is unchanged.
• All test logic (the "missing faker" failure assertion and the successful run with faker installed) is preserved inside the context.

Confidence Score: 5/5

Safe to merge — the change is limited to a single test file and only adds a scoped timeout context around the existing test logic.

The context manager correctly scopes the higher timeout to this one test and restores the original config on exit. No production code is touched, no test assertions are altered, and the retry headroom directly targets a real CI flake caused by slow conda env creation.

No files require special attention.
