END-2: final siege + latching win/lose (SL-3)

At GoalProgress.Charge>=Target a new server-only GoalReachedSystem arms a larger final siege (x live FinalSiegeMultiplier) and flips RunPhase=FinalDefense; CyclePhaseSystem latches a REPLICATED RunOutcome (Victory on clear / Loss on Core breach) and halts the director. RunOutcome is a [GhostField] byte on the global CycleDirector ghost (the client banner observes it); RunPhase stays server-only. ThreatDirector/CoreRestore/CoreDamage halt once decided; SiegeTimeout is off during the final siege. SaveData v5 persists the outcome so a won/lost run loads finished. GoalProgress.Target 10->4. Completes Path A's spine. See DR-036.
