port(m1): wave 6d — Unity method/ctor overloads (572->444)

CS1501 overload gaps (Unity):
- Transform.TransformPoint/InverseTransformPoint(float,float,float); LookAt(.,worldUp) x2.
- Object.FindObjectsOfType(Type)/(bool); Instantiate<T>(.,pos,rot,parent).
- Component/GameObject.BroadcastMessage(string,object[,opts]).
- Animator.Play(string/int, layer[, normalizedTime]).
- Mathf.Min/Max(params float[]/int[]).
- MonoBehaviour.CancelInvoke(string).
