A stolen finger no longer welds you to the edge, and the stack is yours

The right edge is where iOS keeps Control Center, and it is exactly where the
horde's absolute finger-steering parks your thumb. When the system takes that
gesture it delivers neither touchend nor touchcancel: `stick` survives forever,
so every later touchstart falls through to the extra-finger branch (swish, and
only swish) while touchmove ignores the new finger's id. steerPX stays frozen at
0.97 and the player is pinned to the screen edge, melee firing, for the rest of
the run. Any new touch event proves the old finger is gone if it is not in
e.touches — drop the stick then. Verified against the bug: pinned at x=6.11
before, steers to -5.20 after, and a genuine second finger still only swishes.

And wCap 9 -> 99, which is no cap in practice: game 70 wants a bigger stack, not
a rationed one. The barrel weapons move from "paid out only once all four tins
are full" (a branch an uncapped rack would never reach again) to rungs of the
same ladder, so a late duel still hands out a rocket instead of a fifth bomb.
