 * Compare the changed files vs the build output and determine what kind of reload needs to happen:
 *
 * - Do nothing
 *   - CSS or JS file associated with an HTML page is changed - this is handled automatically by the
 *     dev server
 *   - Change isn't used by any of the entrypoints
 * - Reload Content script
 *   - CSS or JS file associated with a content script
 *   - Background script will be told to reload the content script
 * - Reload HTML file
 *   - HTML file itself is saved - HMR doesn't handle this because the HTML pages are pre-rendered
 *   - Chrome is OK reloading the page when the HTML file is changed without reloading the whole
 *     extension. Not sure about firefox, this might need to change to an extension reload
 * - Reload extension
 *   - Background script is changed
 *   - Manifest is different
 * - Restart browser
 *   - web-ext.config.ts (runner config changes)
 * - Full dev server restart
 *   - wxt.config.ts (main config file)
 *   - modules/* (any file related to WXT modules)
 *   - .env (environment variable changed could effect build)
