Function dependency typos currently reach the environment build before
failing. Validate pip requirements with
`packaging.requirements.Requirement` and conda requirements with
Rattler's MatchSpec parser when constructing a function definition,
before source packaging or registration. Errors identify the original
entry and its index.
```python
@lancedb.function(pip=["numpy", "torch>=2.0,,<3"])
def score(value: float) -> float:
return value
# ValueError: invalid pip[1] requirement 'torch>=2.0,,<3': ...
```
Preserves pip extras, markers, named references, bare archive/git URLs,
and conda channel/build specifications. The existing native extension
exposes the conda parser, so no additional Python package is required.
Adds regression coverage for invalid and supported forms, including the
deprecated `udf` alias.
