✨ Updater improvements

[mrkai77]

• Swaps old Loop.app with new Loop.app, rather than first deleting the existing bundle then unarchiving the new app
• Checks for updates 2 seconds after launch, this also helps initialize the Updater class immediately (as static properties are lazily initialized)
• Updater class now has a logger
• Including development updates is now tracked using the Defaults package rather than from within the updater
• Enabling/disabling updates is now also tracked using the Defaults package to reflect defaults write changes

---

This should hopefully fix some issues where Loop.app becomes unlaunchable after updating.

Pull Request Overview

This PR improves the Loop updater system by implementing more robust update mechanisms, better state management, and immediate initialization. The changes focus on replacing the old Combine-based approach with async/await patterns and using the Defaults package for persistent settings.

• Replaces timer-based updates with Task-based async operations for better resource management
• Implements atomic app bundle swapping instead of delete-then-extract pattern for safer updates
• Migrates updater settings to use Defaults package for better persistence and reactivity
