Description​

Generic stage executor whose behavior is supplied by user-provided callbacks.

Wraps a LambdaOnInput (required) and an optional LambdaOnTick so callers can express stage logic inline without subclassing StageExecutor. The bound StagePorts is forwarded to each callback so it can resolve port ids by name.
