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.

+ * has direct importers that are CSS files (e.g., a JS file imports a global CSS file),
+ * this plugin will "touch" those CSS files by updating their access and modification

+ * that the CSS file has changed, potentially triggering a more reliable style reload.
