## Title

    Proposed fix: [CrewAI Flows] RecursionError "Method 'x' has been called 100 times in this flow execution, which indicates an infinite loop" (@listen label matching the method name)

## Body

    Recommended action: Rename router outputs/labels so they do not equal the listening method name; add a loop exit; raise max_method_calls only for intentional long loops.
    
    Option: Rename the label or add an exit condition [evidence: official_recommended_action]
    Applies when: Flows with routers/listeners
    Steps:
    1. @router(...) returns "needs_processing"; @listen("needs_processing") def process(self)
    Expected: Listener runs once per trigger
    
    Evidence basis (self-declared by the contributing chat client): untested.
