- Implemented runtime API for registering custom highlighters. - Added optional Tree-sitter integration for advanced syntax parsing (disabled by default). - Updated buffer initialization and copying to support dynamic highlighter configuration. - Introduced `NullHighlighter` as a fallback for unsupported filetypes. - Enhanced CMake configuration with `KTE_ENABLE_TREESITTER` option.
