fix: allow black to format _generated.py for CI consistency

The CI generates the file and black formats it, but we were excluding it
from black formatting locally. This caused drift between local and CI.

Changes:
- Removed _generated.py from black exclude in pyproject.toml
- Removed _generated.py from black exclude in pre-commit config
- Regenerated file with black formatting applied

This ensures local generation matches CI generation:
- Multi-line imports when > 100 chars
- One export per line in __all__
