Add STATELESS_LAMBDA support to TemplatableValue class using C++20 concepts:
- Automatically detects stateless lambdas (convertible to function pointers)
- Uses 4-byte function pointer instead of 32-byte std::function
- Falls back to std::function for stateful lambdas

Add StatelessLambdaAction and StatelessLambdaCondition classes for automation:
- Memory: 4 bytes vs 32 bytes per lambda
- Direct function pointer calls (no std::function overhead)

This infrastructure enables template platforms to use function pointers for
stateless lambdas, saving ~28 bytes per lambda instance.
