Timothy DeHerrera f9a978bdd6 feat(highlight): implement tree-house syntax highlighting engine ...

Replace tree-sitter-highlight with Helix's tree-house crate for
advanced syntax highlighting:

- Add tree-house and tree-house-bindings dependencies
- Implement SukrLoader with LanguageLoader trait
- Add hierarchical scope resolution with fallback
  (e.g., keyword.control.conditional → keyword.control → keyword)
- Create custom HTML renderer processing HighlightEvents
- Support all 14 languages with Helix queries
- Handle JS/TS inheritance chain (ecma → _javascript/_typescript)

Benefits:
- Richer semantic highlighting with ~75 scope classes
- Proper language injection support
- Hierarchical theme scopes matching Helix themes
- Foundation for converting Helix TOML themes to CSS
