feat: enable source maps for improved debugging

Enable source maps in the webview UI to help with debugging by:
- Adding sourceMap: true to tsconfig.json
- Setting inlineSources: false in tsconfig.json
- Enabling sourcemap: true in vite.config.ts
- Adding source-map package as a dependency

This allows stack traces to be mapped back to original source files,
making it easier to debug issues in the bundled code.
