fix(launcher): show in Dock as well as menubar

LSUIElement=true hid the app from the Dock entirely, which made it
invisible to Cmd-Tab and to anyone who'd rather keep the menubar
clean. Switched to LSUIElement=false so the app shows up in both
places — the menubar status item is still the primary entry point,
the Dock icon is just there for discoverability and Cmd-Tab.
