MP-front scout (task #45): P6 survives the combat rework; LAN-fight gap map

One-box smoke test re-run on the current build: console egg -> mesh ->
RunningMission both instances, 174+ x144-byte update records each side,
2 mech trees per instance, 0 crashes (~6 min). The movement-replication
milestone is intact after all the targeting/weapon/death changes.

Gap map to a first playable LAN fight recorded in
context/multiplayer.md (wiring order): (1) generalize the world-pick
from gEnemyMech to all peer mechs; (2) exercise the Dispatch reroute
for cross-pod TakeDamage; (3) victim state visuals on the shooter's
screen (zone replication or a death event); (4) cross-pod beam visuals
via the AUTHENTIC beam-keepalive messages (FUN_0041c350, templates
@0x511e6c/78 -- already stubbed in emitter.cpp); (5) 2-window driving +
DEATHS scoring; respawn deferred to the P5 teardown debt.
