ConditionPresetEvaluator is a fully stateless utility class. All methods are static. It evaluates a ConditionPreset by:

1. Resolving the left Operand to a float (via the RuntimeEnvironment).
2. Resolving the right Operand to a float (via the RuntimeEnvironment).
3. Applying the ComparisonOp to produce a bool result.

Operand resolution strategy:

• Variable -> query RuntimeEnvironment::GetBlackboardVariable()
• Const -> use Operand::constValue directly (no environment access)
• Pin -> query RuntimeEnvironment::GetDynamicPinValue()

All errors are reported through the outErrorMsg parameter; the return value is always false when an error occurs.

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