Fix unable to uninstall data-protected apps like Clash Party

Previously, apps matching DATA_PROTECTED_BUNDLES patterns (VPNs, dev tools, etc.)
could not be uninstalled because should_protect_path blocked their deletion.
Now use MOLE_UNINSTALL_MODE to distinguish between cleanup and explicit uninstall,
allowing users to remove these apps when they choose to while still protecting
their data during normal cleanup operations.

Also allow deletion of installer receipts in /private/var/db/receipts/.
