Trade the tutorial for a screen that counts the dead

The menus were placeholders next to the art. Three screens now: a title over
an empty, dimmed, blood-stained court; a MATCH SETUP screen where each court
wears meters read straight off its own bounce numbers; and BODY COUNT, which
needed the game to start measuring anything at all.

stats.js keeps one capped array of per-run records — all time, last match and
seven days are three filters over it rather than three counters that can drift
apart. Kills file under the body AND the weapon: killZombie only ever knew an
index, so every damage loop stamps the cause on its way past.

The tutorial is gone. Marvin explained what the in-game modals already teach,
and his stage is where the stats live now.
