Move the trapper resolution block out of sendunitsComplete() into a
dedicated private method calculateTrappedUnits(). It computes how many
incoming attacker units are caught in the defender's traps (Gaul trapper
or Natar capital), updates the trap counters and the prisoners table, and
subtracts the trapped troops from the attacking army.
Pure behaviour-preserving extraction: the inline `${'traped'.$i}`
variables are rehydrated at the call site from the returned bundle, so all
downstream usages remain unchanged.
