The install flow briefly flashed an "Update installed / Restart to use
the new version" callout between clicking Install & restart and the
actual app quit. The button implies action; the restart is already in
flight.
Run quitAndInstall inline (no 1.5s setTimeout) so the IPC sequences
download → install → daemon stop → app quit before returning. Drop the
"installed" rendering branch from the callout so the success path goes
straight from "Installing..." to the window unmounting.
