[WIP] Add Auto-Monitor Toggle with Authorization and Inactivity Notification

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original description:

The user wants to develop a macOS app based on a simple SwiftUI ContentView. The app should include a switch (toggle) for enabling/disabling auto-monitoring of the Notes app. When the user first enables auto-monitoring, the app must prompt the user for authorization to control the Notes app. Once authorized, the app should continue monitoring Notes changes (including changes caused by iCloud sync and edits). Specifically, if a note is edited and then remains unchanged for 15 minutes, the app should trigger a notification and display those changed notes in the UI. We need to update the ContentView.swift and related code to include a toggle switch, request the authorization (simulated with an alert), and simulate monitoring behavior with timers and a list of detected note changes.

The solution should:

1. Modify the base ContentView to have a toggle switch labeled "Auto Monitor Notes".
2. If the user toggles it on for the first time, display an alert explaining that authorization is required. Once the user accepts (via the alert), the app records the authorization and starts monitoring.
3. When monitoring, simulate receiving a note change event (for example, after 5 seconds for demonstration) and use a 15-minute inactivity timer (you may simulate this with a shortened duration for testing) to trigger a notification if no further changes occur.
4. Display the list of detected note change messages in the UI.

The code should be formatted in Swift and include inline comments to explain each section. The project is a macOS SwiftUI app intended for the App Store, so it should include code that complies with the sandbox and automation requirements (though simulation can be used here).

This pull request was created as a result of the following prompt from Copilot chat.
