Slice Combat Depth (MC-3 + wiring + review fixes): Spitter aim-line + player-hit punch, rigged enemies, in-band gate (DR-041)

Completes the Combat Depth slice on top of the MC-2 server spine (56cf60cce):

MC-3 impact juice (client, observe-only):
- 7 FeelConfig fields + ResetDefaults; magnitude-scaled player-dealt-hit camera
  PunchFov on the enemy-Health-decrease edge (camera-only hit-stop, never timeScale).
- Spitter Kind==2 aim-LANE telegraph (BuildLaneMesh) — reads baked SpitterState
  client-side, falls back to a fixed length. True freeze + material flash deferred.

Content / wiring:
- SpitterProjectilePrefabAuthoring (the SpitterProjectilePrefab singleton).
- Both directors rebuilt to a 4-entry KIND-INDEXED roster [Grunt,Charger,Spitter,
  Swarmer] + mix/MaxAlive config + the SpitterProjectileConfig singleton in the subscene.
- Real rigged models: EnemySpitter (re-skinned Kaiju, ranged poker) + EnemySwarmerUndead
  (Undead-Werewolf, fast/low-HP); grunt/charger keep Werewolf/ChargerMuscle. EnemySpit =
  ownerless interpolated ghost (no Health, no collider).

Post-impl adversarial review fixes (wf_febdcfdb-665):
- [MED] in-band fire gate: the Spitter committed its telegraph from ANY range (fired while
  advancing from far). Now commits only when sInBand || sCornered (gives CorneredRange a
  real read site) — a Spitter out-of-band holds fire and repositions.
- [LOW] EnemyProjectileDamageSystem early-returns on !ServerTick.IsValid (sibling parity).
- [LOW] EnemyAuthoring bake-time guard: errors if a prefab composes both Charger+Spitter
  (would match zero AI passes -> never move).
- [LOW] tests: Spitter brain fires from Expedition (kills the Base==0 region false-green);
  a direct partition-exclusion test replaces the order-masked claim; added out-of-band +
  cornered negative tests.

388/388 EditMode green + two Play smokes (clean boot, fire, swept-hit, region, server==
client; rigged Kaiju spitter bakes + fires with zero console errors). Accepted as-is
(documented in DR-041): global spit soft-cap, co-op punch attribution.
