app.quit() does not stop a lock-losing instance from reaching whenReady:
the before-quit teardown coordinator defers the quit (event.preventDefault
+ async backend shutdown), and ready fires in that window. The losing
instance then runs the full startup whose reapOrphans() SIGTERMs the
running instance's live backend (#87295).
The lock-loser holds no state and no backend — requestSingleInstanceLock()
has already delivered the argv to the primary by the time it returns false —
so there is nothing to clean up. app.exit(0) terminates immediately, before
ready, so a second launch routes into the running window and never touches
backend machinery.
