BT decorator that instantiates and runs a subtree within the larger tree. BTSubtree instantiates a [BehaviorTree] and includes its root task as a child during initialization, while also creating a new [Blackboard] scope. Returns the status of the subtree's execution. Subtree blackboard variables can be mapped to the main tree blackboard plan variables. Check out mapping section in the inspector. Note: BTSubTree is designed as a simpler loader, and does not support updating [member subtree] at runtime. A custom subtree decorator is better suited and [url=https://github.com/limbonaut/limboai/issues/94#issuecomment-2068833610]somewhat trivial[/url] to implement. A [BehaviorTree] resource that will be instantiated as a subtree.
