NuconSimulator now accepts uncertainty_threshold (default None = disabled).
When set and using a kNN model, _update_reactor_state() calls
forward_with_uncertainty() and raises HighUncertaintyError if the GP
posterior std exceeds the threshold.
NuconEnv and NuconGoalEnv catch HighUncertaintyError in step() and
return truncated=True, so SB3 bootstraps the value rather than treating
OOD regions as terminal states.
Usage:
simulator = NuconSimulator(uncertainty_threshold=0.3)
# episodes are cut short when the policy wanders OOD
