Notes

• show() does not require any permission and is available to all plugins. Use it for routine feedback (success confirmations, transient errors, progress updates).
• notify() requires the notifications permission declared in manifest.json. Use it sparingly for important events the user needs to see even when AMC is not focused.
• Toast messages from show() auto-dismiss after a few seconds. The user does not need to interact with them.
• OS notifications from notify() follow the operating system's notification behavior (sound, banner, action center, etc.).
