Switch to uv - python

[MonkeyCanCode]

This PR is created on top of #205, LICENSE and NOTICED are added here for completeness. These two files would be remove if the reference PR got merged first.

As per ML, we want to proceed with more standard layout for python project by using uv. Here are the changes made in this PR:

1. Added LICENSE and NOTICE (see above for reference)
2. Added README.md with instructions around uv
3. Updated pyproject.toml with PEP 639
4. Added authors, readme, keywords, project.urls in pyproject.toml
5. Removed redundant classifiers in pyproject.toml as that is covered by requires-python
6. Removed pytest dependency as this project doesn't have any unit test
7. Refresh uv.lock

Can you please remove the LICENSE and NOTICE file for now? The "root" ones are good enough.
