Every run gets a door out: the quit chip and the LEAVE THE MATCH? ask

"all tennis screens are missing the ability to exit the game and return to
the menu — right now I need to force close the app." A quiet x chip rides the
top-right corner of every run (the scoreboard owns the left; the desktop key
hint shifts inboard). Tapping it — or Escape on desktop — freezes the world
with the existing paused flag and asks LEAVE THE MATCH?: BACK TO THE MENU in
the menu's crimson, PLAY ON underneath. Quitting is the death path minus the
death — restartRun, refreshSplash, splash — and banks nothing: an abandoned
run never happened, statistically. Verified live both ways: PLAY ON resumes
the frozen rally, quitting lands on the splash with the chip retired.
