END-1: the base can be lost - a losable Engine Core with integrity

Adds CoreIntegrity{[GhostField] Current,Max,OverrunTick} on the GLOBAL
CycleDirector ghost (no new ghost/relevancy). CoreDamageSystem (server,
after EnemyAISystem): a Husk within ~3u of PlotCenter drains + is consumed;
CoreRestoreSystem regenerates only in Calm. The SOFT-loss edge lives inside
CyclePhaseSystem (sole Phase writer): Current<=0 in Siege flips to Calm with
NO goal reward, StorageMath.DrainFraction drains the shared ledger, all Husks
despawn, and OverrunTick is stamped (a transient HUD-flash pulse, not a
latching outcome - the Victory latch is END-2's). EnemyAISystem treats the
Core as a FALLBACK target so an undefended base is overrun instead of idling.
SaveData -> v4 persists CoreCurrent (0 -> born full, the EB-1 HP sentinel);
3 live TuningConfig knobs + a red HUD Core bar. Soft-loss + targeting +
breach-resolution forks operator-locked.
