When a ConditionPreset uses a Pin-mode operand, the owning NodeBranch needs a physical input pin rendered in the graph editor. A DynamicDataPin tracks all metadata required to:

• Render the pin in the node UI.
• Map incoming float data to the correct operand side of the correct condition during runtime evaluation.
• Persist to JSON alongside the node so that connections survive save/load.

Each DynamicDataPin has a globally unique UUID so that graph links can reference it by ID without ambiguity.

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