Typing stubs for VapourSynth

vs-stubs provides Python type stubs for VapourSynth plugins and core functions. This helps editors, IDEs, and static type checkers (e.g. mypy, pyright) understand VapourSynth's API.

Due to the dynamic nature of VapourSynth's plugin system, any newly installed plugins are not automatically reflected in the stubs. When adding plugins, you will need to regenerate stubs to keep the type information accurate and in sync with your environment.

Note that vs-stubs does not include or install any actual VapourSynth plugins. Only their type definitions.
