ComfyUI-FrontendPatches

Fixes core ComfyUI frontend issues that affect custom node development:
- Vue reactivity blindness (slots don't re-render after addInput/removeInput)
- ChangeTracker only knows INPUT/TEXTAREA (breaks CodeMirror, Monaco, etc.)
- LiteGraph event capture (blocks custom UI interaction)

This extension applies patches automatically. Other extensions can use the
JavaScript API for additional control.

See README.md for documentation.
