Triple-tap the scoreboard for a sandbox

A test mode for trying the new content without playing twenty games to reach it.
Three taps on the scoreboard toggles it, three more turns it off, and a single
tap is still the miss-log overlay. Same shape as the umpire triple-tap cheat it
sits next to.

It OVERRIDES the difficulty director rather than editing it, so the wave is the
same whether you opened it in game 1 or game 40 and the run keeps running
underneath: 8 bodies, a fixed 1.15 m/s shamble, a spawn every 1.6 s, and
pickVariant pretending to be at game 20 so every body type can turn up. All four
barrel weapons sit on the rack and are topped back up each frame, because
committing a burst spends the whole tin and a sandbox that runs dry is not one.
A barrel rolls out every 14 s so the pickup itself is testable too.

The third tap must NOT toggle logShow: taps one and two already toggled it twice
and it is back where it started, so toggling again left the miss-log overlay
switched on behind you every single time.

Also records the trap that cost a debugging round getting here: index.html loads
main.js?v=N, and fetching 'main.js' does not bust that URL -- so main.js stayed
stale through a reload while every other module was fresh, and the tap handler
appeared to do nothing.
