Module executor 

Step executor — reconstructs operations from configs and runs them.

Each step type (shell, HTTP, agent) has its own executor implementing the StepExecutor trait. The execute_step_config function dispatches to the appropriate executor based on the StepConfig variant.

Every executor declares the StepKind it handles via StepExecutor::kind, and execute_step_config derives the span and metric label from that kind. A new step type therefore only has to declare its kind instead of extending a match here.
