Python bindings for ghostty-vt

Changes were minimal, just small pyproject.toml and build.py (hatch_build.py) changes to use PEP 621 standard.

We also reconfigure to a self-managed zig build. This means pytest no longer runs Zig tests automatically, you must manually run them.

Environment:

pyenv local 3.13.1 # set python version
uv sync # install dependencies

Build and run tests:

uv run pytest # run python tests
uv run zig build test -Dpython-exe=$(uv python find) # run zig tests

Note the -Dpython-exe=$(uv python find) flag is required to avoid a codepath in pydust that shells out to poetry.

• All done with ziggy-pydust==0.25.1
• On a Mac with M1 (ARM) chip
• Using zig 0.14.0
• Using python 3.13.1
  • IMPORTANT: python must be installed with pyenv, not brew. The python from brew comes in Framework format, which breaks pydust's build process due to how the path is parsed.
