required deps should be installed with pacman (the same pacboy field used above) or inside of venv

Summary
Add a focused MSYS2/MinGW CI job to the tests workflow so source builds are exercised under MSYS2 Python and the MinGW Rust/GCC toolchain.
The job currently runs for UCRT64 and MINGW64, installs MSYS2-packaged Python, pip, maturin, Rust, and GCC, then builds this repo from source with pip and smoke-tests the installed extension import. This is intended to catch failures like #109 where PyO3/MinGW linking breaks even though the normal Windows/MSVC path still passes.
Validation
