Pull request overview

This PR refactors the Monaco Monarch language definitions for G-code, Klipper config, and Moonraker config, aligning folding + theming with the new token scopes and adding unit tests to pin tokenizer behavior.

Changes:

• Refined Monarch tokenization rules for gcode, klipper-config, and moonraker-config (including new token categories used by themes).
• Updated folding-range worker logic for region markers, comments, and SAVE_CONFIG handling.
• Added Vitest tokenizer tests (plus jsdom polyfills) and updated documentation to reflect the new highlighting behavior.
