ManipulationStateMachine

ManipulationStateMachine

Core state machine for managing manipulation modes. Uses string-based mode identifiers instead of concrete state classes, following composition over inheritance pattern for AOT compatibility. This is the pure C# implementation - the Godot layer wraps this with Node-based states if needed.
