Fix PyPI release workflow for Maturin/Rust extension

python -m build produces a bare linux_x86_64 wheel which PyPI rejects
(400 Bad Request) — platform wheels must be manylinux-tagged.

Replace with the standard PyO3/maturin-action matrix that builds:
- Linux x86_64 + aarch64 (manylinux auto)
- Windows x64
- macOS x86_64 + aarch64
- Source distribution

All artifacts are collected and published in a single upload job.
