- Plaintext passwords are no longer saved to disk or logged — credentials are kept in-memory only for the current session.
- Added a password field in the UI with a prompt on connect when credentials are needed.
- SMB provider now supports
smb://and UNC path parsing, with Linux share resolution via GVFS (gio mount). - Clearer error reporting when mounts or authentication fail.
