Describe the bug

When the "Automatically check for updates" checkbox is unchecked in Preferences > General, MonitorControl continues to make network requests to monitorcontrol.app, github.com, and githubusercontent.com. Network monitoring software (firewall/network control tools) still shows these connection attempts despite the preference being disabled.

Steps to reproduce

1. Open MonitorControl Preferences
2. Go to 'General' tab
3. Uncheck 'Automatically check for updates'
4. Close preferences and restart the app
5. Monitor network activity with firewall/network control software
6. Observe connection attempts to monitorcontrol.app, github.com, and githubusercontent.com

Expected behavior

When "Automatically check for updates" is unchecked, the app should not make any network requests or initialize the Sparkle updater framework. Network activity should only occur when manually clicking "Check for updates" in the About preferences.

Anything else?

Root cause: AppDelegate.swift line 68 unconditionally calls updaterController.startUpdater()
regardless of the SUEnableAutomaticChecks preference setting. The checkbox only sets the
preference but doesn't prevent the updater from initializing and making network requests.

Suggested fix: Wrap line 68 in a conditional check:
if prefs.bool(forKey: PrefKey.SUEnableAutomaticChecks.rawValue) {
self.updaterController.startUpdater()
}
