MasterSafe Authenticator 1.3.1

Added

• Recovery: "Create recovery key automatically". MasterSafe chooses a strong random passphrase (30 characters, no look-alike letters), asks where to save the key file, and shows the passphrase once with a Copy button so it can be written down. Nothing is set up if the file is not saved. Choosing your own passphrase still works.

Fixed

• Choosing an icon for a folder did nothing: the picker closed before the choice was applied. It now changes the icon and then closes.
• Attached file names use the same strict rules on every system (no :, *, ? and so on), so a name is safe wherever the vault is opened.
• The release workflow signs the Linux packages on a Windows runner, because the Ubuntu runner cannot create ML-DSA signatures.
