Introduces a new Value Source entity that produces a scalar float (0.0-1.0) for dynamic brightness modulation. Three subtypes: Static (constant), Animated (sine/triangle/square/sawtooth waveform), and Audio-reactive (RMS/peak/beat from mono audio source). Value sources can be optionally attached to LED targets to control brightness each frame. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
