- Add comprehensive JSDoc annotations to FoundryAdapter.js methods (settings, socket, users, scenes, notifications, hooks)
- Add /* global Dialog */ comment to PlayerPrivacyPanel.js for ESLint
- Remove unused _force parameter from GMPlayerPrivacySelector.js render() method
- Fix PlayerPrivacyPanelMenu.js: add constructor() to fallback class and call super()
