Apply code formatting fixes for pre-commit compatibility (SD-694)

[duolingo-baymax]

Summary

Applies auto-formatting fixes to pass the new duolingo/jenkins/pre-commit CI check, which runs uvx pre-commit run --all-files without skipping any hooks.

No hooks were renamed or removed. The duolingo hook from duolingo/pre-commit-hooks applied standard formatting fixes to 4 files:

• Fixed spacing around inline comments and type annotations
• Reformatted long import lines
• Sorted pyproject.toml keys
• Removed trailing blank lines

Test Plan

• Verified uvx pre-commit run --all-files passes locally

Verification Steps

• All pre-commit hooks pass
