[FEATURE] Look into and clean up login and extension items when uninstalling an app

[pingshunhuangalex]

Feature description

I noticed that when OBS is uninstalled, the OBS virtual camera extension is still left behind. Not sure if it's something that can be scanned and cleaned up.

Forgot to take a screenshot, but I removed it via system settings > general > by category > camera extension

Good catch! System extensions (camera, network, endpoint security, etc.) are SIP-protected, so Mole cannot remove them programmatically.

I've added post-uninstall detection: after removing an app, Mole now checks /Library/SystemExtensions for orphaned extensions matching the app's bundle ID. If any are found, it shows a warning pointing users to System Settings > General > Login Items & Extensions to clean them up manually.

This follows the same pattern as the existing Local Network permissions warning.
