build.py

"""Build Pub-Streamer into a standalone Windows executable using Nuitka.

Usage (from project root):
    uv run python build.py

On CI the GITHUB_ACTIONS env var is set automatically, which switches the
compiler to MinGW (GCC) — it handles the large generated C files that cause
MSVC to run out of heap on constrained machines.
