Error:

TypeError: randint() requires integer arguments (parameter: flowControlThresholdLagPercentage).
Got min=0.0 (type=float), max=1.0 (type=float).

Description:

The runtime parameter fuzzer was using generate_normal_mongo_parameters() for all parameters, but flowControlThresholdLagPercentage requires special handling that only existed in the startup code path.

At startup, generate_flow_control_parameters() uses rng.random() for this parameter. At runtime, the generic function tried to call randint() on float min/max values, which fails in Python 3.13.
