GraphRuntimeInstance wraps a TaskGraphTemplate and manages the runtime state needed to execute it step-by-step. It owns a RuntimeEnvironment (Blackboard + dynamic pin values) and an execution stack.

Execution model:

• StartExecution() initialises the stack from the graph's entry node.
• StepExecution() advances by one node, evaluating Branch conditions using ConditionEvaluator.
• IsExecuting() returns false when the stack is empty (done or error).

Branch node evaluation:

• Each NodeConditionRef is evaluated in order against the environment.
• Multiple conditions are combined using their LogicalOp (And / Or).
• When the combined result is true the node's NextOnSuccess path is taken; otherwise NextOnFailure.

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