- Add entropy field to EffectConfig (0.0 = calm, 1.0 = chaotic) - Provide compute_entropy() method in EffectContext for dynamic scoring - Update Fade, Firehose, Glitch, Noise plugin defaults with entropy values - Enables finer control: intensity (strength) vs entropy (randomness) This separates deterministic effect strength from probabilistic chaos, allowing more expressive control in UI panel and presets. Fixes #32
