- Add full JS feature support to Negative Prompt Node (Token Counter, BREAK markers, and Autocomplete).
- Implement smart "Effective Prompt" visibility: the expanded prompt view (used for TIPO/Wildcards) now automatically hides if it's identical to the user input.
- Refine Autocomplete logic: suppress the popup when deleting separator characters (commas, spaces, brackets, etc.) via Backspace to prevent unnecessary re-opening on finished tags.
