ArdaandClaude Opus 4.6 55f76d60df Add Device > Discover menu with standalone discovery dialog
Discover dialog shows a device list with Port, Wait Time fields and a
Discover button. Selecting a device and clicking Connect (or double-
clicking) opens a credentials prompt for username/password, then
connects. The Connect dialog is reverted to its original simple form.
