Update to master 2026-08-10

[arsym-dev]

Builds on #5

• Added typing for remaining files. The first batch are manual, but the last batch was assisted with agents.
• Updated from the old 8.5.3 branch to 8.6.0. Might still be missing a few types but should be minor
• Added instructions to integrate with main repo (both as a stub repo and to inject types back into source files)
• Improved scripts (particularly inject). Much easier to run now.

To address your concerns:

1. I have not included py.typed but everything operates fine without it. Feel free to add it if you like. Removed scripts/init.py
2. Fixed
3. Kept as instructed
4. Now uses pathlib over os.path
5. Now uses uv rather than pip
6. Preserving pyx docstrings will be addressed in a later PR

You can try it yourself by cloning this repo into the typings directory in renpy, checking out the master-2026-08-10 branch, and modify the pyproject.toml to have this:

[tool.pyright]
stubPath = "typings/renpy-stubs/src"

exclude = [
    "**/node_modules",
    "**/__pycache__",
    "**/.*",
    ".venv",
    "typings/",
    "module/build/",
]
