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.

+/**
+ * Creates a Vite plugin designed to gracefully handle the conclusion of the build process.
+ * This plugin utilizes the `buildEnd` and `closeBundle` hooks provided by Vite.
+ * It checks for errors at the end of the build:
+ * - If an error occurred during the build (`buildEnd` hook receives an error), it logs the error
+ *   and explicitly exits the Node.js process with a status code of 1 (indicating failure).
+ * - If the build completes without errors and the bundle is successfully generated
+ *   (`closeBundle` hook is called), it logs a success message and exits the process
+ *   with a status code of 0 (indicating success).
+ * This explicit process exiting can be useful in CI/CD environments or scripts that
+ * rely on the process status code to determine the build outcome.
+ * The core logic for using these hooks to exit the process is inspired by
+ * a solution found on StackOverflow (https://stackoverflow.com/a/76920975).
+ *
+ * @returns {Plugin} A Vite plugin object configured with `name`, `buildEnd`, and `closeBundle` hooks.
