- Create src/highlighter.rs with OnceLock-based one-time syntect initialization - Implement init_highlighter(), syntax_set(), theme_set() accessors - Implement syntect_color_to_cga() with Euclidean RGB-to-CGA 16-color quantization - Implement highlight_code() returning Vec<Line<'static>> using base16-ocean.dark theme - LinesWithNewlines iterator preserves newlines for syntect grammar correctness - Module verified to compile cleanly (tested via temporary mod registration)
