Started without a command, keeporg now shows a padlock in the system tray with a menu like midi-webhook's: a status line, the mirror folder, each database with its state, Sync Now, browser sign-in and sign-out, the web interface, the configuration, the log, Start at Login, About and Quit. The commands are unchanged. config.json now carries every client setting (device_label, request_timeout_seconds, ca_file, log_file, notifications), is written in full on first start and is reloaded by the tray when saved. A lock in the mirror directory admits one agent at a time, since the tray, `keeporg run` and a service unit could otherwise race each other. The tray uses fyne.io/systray: pure Go on Linux, BSD and Windows, cgo on macOS only. The server keeps no third-party dependencies. Desktop versions go to 0.5.0.
