BTtoVSMigrator translates a "BehaviorTree" schema_version 2 (or lower) JSON document to the ATS VisualScript schema_version 4 format consumed by TaskGraphLoader.

Node type mapping: BT v2 type -> VS v4 TaskNodeType ───────────────────────────────────────── "Selector" -> TaskNodeType::Branch (conditions as children) "Sequence" -> TaskNodeType::VSSequence "Action" -> TaskNodeType::AtomicTask "Condition" -> TaskNodeType::Branch (single condition leaf) "Decorator" -> TaskNodeType::AtomicTask (inline, stripped) "Root" / "Start" -> TaskNodeType::EntryPoint

Connection mapping: BT parent->child -> ExecPinConnection { parent, "Out", child, "In" }

Blackboard mapping: BT blackboard entries are copied verbatim to the VS graph's Blackboard.

C++14 compliant — no std::optional, structured bindings, std::filesystem.
