experiment-rollouts

Gradual (staged) rollouts for Gamebeast experiments: how the rollout gate and its smooth ramp curve work, the curve presets, turning a ramp request into rollout steps for create_experiment, reading a rollout from get_experiment and get_experiment_results, and operating one with update_experiment_rollout (set, advance, pause, resume, replaceSteps). Load before designing, changing, or explaining any experiment rollout.
