Fix local changes detection

Do not use diff as this only detects modified files, but not added ones.
Run status --porcelain instead and check if there is any output.

+#### What happens to local changes
+
+Any local changes are stored in a backup branch and then reset and cleaned up. No local changes should be commited or synced up, this would break the pull only flow.
+
+If there are changes and they have been reset it will show up in the log like this
+
+```log
+...
+[2026-01-22 14:31:02] [F4222EC4] [!] Local or cached changes detected, creating backup branch and resetting changes
+[2026-01-22 14:31:02] [F4222EC4] Reset log: HEAD is now at 633f6de Uppdate 14
+...
+```
+
+If a clean up was run too it will show up as "Clean log" after the Reset log.
+
+The reset will only reset local or cached changs (added) but not changed that have been commited. If changes have been commited a manual reset has to be done.
+
 ## TODO
 
 Future versions will hold an incoming webhook handler and a polling scripts (systemd based)
