Fix the landed-toast softlock: the drawer no longer opens before Rapier is up

The toast could beat the wasm: main.ts boots the game without awaiting
game.init(), and drawer.reset() dereferences the Rapier World. Pop early
enough on a slow device and onPopped -> openDrawer threw mid-update,
leaving the round on phase 'landed' with an empty hint and a dead ENTER
(field report: toast apparently resting against the toaster, game stuck).

- Game.init() is memoised with a drawerReady flag; a second call joins
  the first instead of building a second World.
- openDrawer() and the fromLoaf knife-trip both gate on it: wait for
  physics if it's still compiling, and if it never arrives, degrade to
  handing over the ordered tool instead of softlocking.
- Belt and braces in the kitchen: a 3s flying timeout force-lands the
  slice, so 'flying' can never hang mid-air whatever the cause.
