Pull request overview

Updates the backend’s Pyrefly type-check configuration and local exclusion list to reduce the number of files skipped during local type-checking, continuing the Pyrefly workflow introduced in #33059.

Changes:

• Shrinks/refines api/pyrefly-local-excludes.txt to exclude fewer broad areas (notably replacing a prior broad VDB exclusion with more targeted entries).
• Updates [tool.pyrefly] settings in api/pyproject.toml (infer-with-first-use and min-severity).
