Adds the server-authoritative mechanics for three new enemy archetypes on top of the Grunt/Charger base, plus the weighted wave-composition that introduces them: - Spitter: a ranged Husk variant (SpitterState) that holds a preferred range-band (advance/retreat/hold via EnemyAIMath.BandVelocity) and fires a telegraphed, dodgeable EnemyProjectile. New server EnemyProjectileMoveSystem (integrate + store LastStep) + EnemyProjectileDamageSystem (region-filtered swept hit-test rebuilt from LastStep — DR-018 anti-tunnelling; players use HitRadius, structures a const radius; at-most-once destroy). Concurrent-spit soft cap, soft-fail retry. - Swarmer: marker tag + deterministic cluster spawn (1 slot = 1 pack; EnemyAIMath.ClusterOffset), MaxAlive counts ENTITIES so a pack defers if it won't fit. - 4-type weighted mix: MixBands -> ZoneEnemyMath.WaveSlots/KindForSlot/ PackSizeForSlot drives both the expedition director and (fork-4a) the base siege, with a mandatory MaxAlive cap. Legacy WaveSize/IsChargerSlot kept + parity-tested. - Discriminator stays component-presence (no enum in Bursted systems): query- partition guards keep each enemy moved by exactly one EnemyAISystem pass (sole-Position-writer). EnemyTelegraph.IsCharger -> Kind byte for the client cue. New authoring (Spitter/Swarmer/EnemyProjectile) + expanded director authorings with tunable mix/cluster defaults. 13 new EditMode tests (mix composition + legacy parity, band/cluster math, projectile move + cross-region + swept anti-tunnelling regressions); full suite green before commit. Dormant until the prefab/subscene wiring lands (next): the new systems guard on TryGetSingleton/RequireForUpdate, so with no prefabs wired the new types stay inert.
