lancedb-gatefixer[bot] ca60b402aa fix(python): reject invalid punctuation in UDF names (#4724)
Function names containing periods or hyphens passed `@udf` validation
and failed only when registered with the server. Restrict the name
pattern to ASCII letters, digits, and underscores, preserving the
existing first-character rule so invalid names fail when the decorator
runs.

Document the accepted format and add regression coverage for dotted and
hyphenated names, including trailing punctuation, alongside valid name
overrides.

Fixes #4720

Validation:

- The four new invalid-name cases failed before the validator change
because no `ValueError` was raised.
- `cd python && uv run --extra tests pytest
python/tests/test_first_class_function_slice2.py -q`: 86 passed.
- Ruff 0.9.9: `ruff check python` and `ruff format --check python`
passed.
- Repository-root `ruff check .` reports 48 pre-existing errors in
`docs/web-tests/`.
