Manages placement mode state as a proper state machine. Replaces the overlapping BuildMode and PlaceSubmode enums, eliminating the mode-flap bug class caused by inconsistent state combinations and the "no place-pending value" hack. [b]States:[/b] IDLE — Not placing anything. Maps to ModeState.OFF ROUTER — PLACE mode active, waiting for tool/category selection OBJECT — Actively placing an object (placeable selected) TERRAIN — Actively painting terrain (terrain name selected) [b]Two-way sync with ModeState:[/b] Out: IDLE → OFF, all others → PLACE (canonical) In: non-PLACE/BUILD modes force IDLE (MOVE/DEMOLISH/INFO/OFF) Scene-free (extends RefCounted). Directly unit-testable.
