physics: character controller (Jolt CharacterVirtual)
- CharacterControllerComponent: capsule params (radius/halfHeight, mass,
max slope, step height); entity origin = feet via shape offset
- CharacterController per-entity wrapper: gravity integration + grounded
clamp, ExtendedUpdate (sweep/slide + stick-to-floor + walk-stairs),
SetLinearVelocity/Jump/IsGrounded facade
- PhysicsWorld: SyncCharacters reconcile (create/rebuild on param
change, editor-drag teleport), UpdateCharacters after physics Update
(Jolt recommended order), writes back to Transform
- Inspector: params + grounded/velocity telemetry + jump debug button
- Serialization: params only, state rebuilt by reconcile
