"""Gitea #46 -- verify the ammo bay fire detonates and applies real damage.

Before this fix, three stacked defects made an armed bay fire permanently inert:
the clock stub (`0 < 0` never fired), the InjectHeat no-op (nothing applied),
and the never-stamped Damage record (0 damage of type 0 even if it had).

Rig: BT_BAYTEST=<frame> sends message 1 (the crit-induced "begin cook-off
countdown", @004bdb94) to the first AmmoBin.  The authentic fuse is a FIXED
10.0 seconds (raw disasm @004bd450: 10.0 x ticksPerSecond + 0.5, __ftol --
the old "RandomDelay" was a Ghidra artifact).

PASS =
  [ammo] ... BAY FIRE (message): cook-off armed, N rounds, detonation in 10s
  ...~10 wall seconds later...
  [ammo] ... BAY FIRE DETONATION: N rounds x D = total (type T)
  ammo explosion damaging <zoneName>          (the binary's exact @0050df61 print)
  ...and the mech takes real zone damage (BT_MP_NET handler line / DAMAGE state).

Kills only the PID it spawns.
