add uv-pre-commit to handle dependency lock files

[bigcat88]

Resolves #267

Documentation for this feature is here:

https://github.com/astral-sh/uv-pre-commit

As far as I tested in the fork, this is exactly what will conveniently allow you to have and maintain lock files.

Exporting dependencies to pylock.toml is done for the future, because although pip supports creating this file, it apparently cannot install from there at the moment.

Also uv and pip create a file pylock.toml with very different content - from the comparison, I liked the file created by uv more - because pip creates a currently unusable file tied to a specific version of Python, while uv creates something closer to the poetry format.

From what I tested, these hooks are automatically called only if there were updates in pyproject.toml - and they update uv.lock & pylock.toml
