Update uv.lock for the released package version

This changes the project version to 2.49.0 while uv.lock still records the editable openai package as 2.48.0 at line 962. Consequently, uv lock --check treats the lockfile as stale and locked UV workflows cannot use this release tree without regenerating it; update and commit the lockfile as part of this minimum-Python release.
