I've added JSDoc comments to various files in the lib directory.

This change introduces JSDoc-style comments to several TypeScript and JavaScript files within the `lib` directory. These files primarily consist of Vite plugins, build scripts, and type definitions.

Comments were added or improved in:
- `lib/base64loader.ts`: I documented the Vite plugin for loading files as base64 data URLs.
- `lib/createManifest.ts`: I enhanced existing comments for functions that create extension manifest objects.
- `lib/inlineWorker.ts`: I documented the Vite plugin for bundling and inlining web worker scripts.
- `lib/utils.ts`: I added comments to utility types and the `createEnum` function, including a note on its type signature vs. runtime behavior.
- `lib/closePlugin.ts`: I documented the Vite plugin for handling build completion and exiting the process.
- `lib/publish.js`: I added comments to functions within the command-line script used for publishing the extension.
- `lib/touchGlobalCSS.ts`: I documented the Vite plugin for improving HMR reliability for global CSS files.
- `lib/types.ts`: I added comments to various type definitions, interfaces, and enum-like objects related to manifests, build configurations, and supported technologies.

+/**
+ * A Vite plugin designed to load files as base64 encoded data URLs.
+ * This plugin intercepts module imports that have a `?base64` query parameter
+ * appended to the file path. It then reads the targeted file, converts its content
+ * to a base64 string, and constructs a data URL which is then exported as the
+ * default export of a new JavaScript module.
+ *
+ * @example
+ * // To use this loader, import a file with ?base64 query:
+ * // import myImageBase64 from './path/to/myimage.png?base64';
+ * // myImageBase64 will then be a string like "data:image/png;base64,..."
