This PR introduces several performance improvements to the Material Theme Builder: 1. **Memoized kebab-case conversion**: Added a Map-based cache to `toKebabCase` utility to avoid redundant regex operations when processing dozens of color tokens on every input change. 2. **Constructable Stylesheets**: Refactored the theme application logic to use a singleton `CSSStyleSheet` with `replaceSync`, significantly reducing the overhead of updating document styles compared to re-creating and re-attaching stylesheets. 3. **Optimized CSS string building**: Replaced inefficient `reduce` chains and multiple global `replaceAll` calls with streamlined loops. The new implementation generates both raw CSS for the document and formatted CSS for the code preview in a single pass. 4. **Build stability fixes**: Fixed build failures caused by missing `.js` extensions in `@material/material-color-utilities` and updated `@sandlada/material-design-css` import paths to match the current environment's file structure. These changes make the real-time theme preview feel more responsive, especially when using sliders or color pickers.
