chore: use uv build to build the package

[KazuCocoa]

This PR keeps setup.py for compatibility purposes, but we'll be able to delete it. Then, maybe it makes sense to bump the major version.

This PR still keeps current release.sh method yet.

Pull Request Overview

This PR migrates the package build system from using setup.py sdist to uv build while maintaining backward compatibility by keeping setup.py for now. The changes modernize the build process by leveraging pyproject.toml as the primary configuration source.

Key changes:

• Modified setup.py to read configuration from pyproject.toml instead of hardcoded values
• Updated build script to use uv build instead of python setup.py sdist
• Moved package metadata from dynamic to static configuration in pyproject.toml

should we also have a TODO to remove release.py? I assume all uv-specific steps could be moved to a makefile script instead

I assume release.py itself can be removed without major version update. I'm still modifying for it so still haven't ended with comment
