[chore] Migrate from setup.py to pyproject (#38)

### TL;DR

Migrated from `setup.py` to `pyproject.toml` for modern Python packaging.

### What changed?

- Replaced `setup.py` with `pyproject.toml` for package configuration
- Updated GitHub workflows to use `pyproject.toml` instead of `setup.py` for caching
- Changed build process to use `python -m build` instead of `python setup.py sdist bdist_wheel`
- Removed `MANIFEST.in` as package data is now defined in `pyproject.toml`
