Actor: move all AI code under Game/Actor

Link order shows one sorted actor tree, not a separate AI project: the
Action/AI/Query folders and per-feature folders (Camera, Player, Horse,
...) come out of the same archive rounds as the actor classes.

(AI assisted using Claude Fable 5.1 and Claude Opus 5.5)
