G6+G4: Cone damage-at-contact + zone fill telegraph (ZoneEffect GhostFields) + co-op saturation budget

Cone/SpecialSlam damage lands at its visual contact via ConeContactPending (knob 32, 0=legacy;
early-flush + resolve re-validate; death + BOTH class-swap paths drop armed pendings — fixes the
shipped melee death-strand in the same stroke). Zones: [GhostField] Caster/Radius/NextTick +
ZoneTelegraphSystem (Geyser latch contract on InterpolationTick; rim = true radius; arm grows,
persistent phase drains). Cone cues latch to contact (FireStartRaw, C14); TuningConfig.Defaults()
fallback at client cue sites (release-build timing fix). G4: SaturationMath ally-FX degrade
(living-enemy census, solo-exempt; enemy telegraphs structurally exempt) + CombatStressDebug +
overlay saturation rows. Reviews wf_98bf1268 (13 confirmed folded) / wf_9757d214 (5 confirmed fixed).
