desktop: v0.1.19 — reliable auto-update for close-to-tray users

The app closes to tray, so it kept running on the old version and only checked on a fresh launch.
Now: (1) check for updates on EVERY window show (X-to-tray then reopen, taskbar, relaunch via
second-instance) via win.on('show'), throttled 1/10min; (2) explicit autoInstallOnAppQuit=true so
a downloaded update installs on the next real quit / PC restart even if the user never clicks
"Restart now"; (3) native notification when an update finishes downloading while hidden in the
tray. The existing 6-hour background timer is unchanged and still runs regardless of window state.
Also carries the 0.1.18 downloads-to-Downloads-folder change.
