Energy Gradient Signal Integration
This module formalizes energy decrease/increase as gradient signals that integrate
into the waveform-waveprobe pipeline.
Key structures:
- EnergyGradient: temporal and spatial energy gradients
- EnergyWaveform: gradient encoded as waveform
- EnergySignal: energy gradient with noise
- ThermodynamicChannel: energy information channels
- ShapeEnergyCoupling: coupling between shape and energy gradients
