LYGO TruthLightEcho v0.1
Generates harmonic echo sequences from ∫Truth×Light metrics.

Integrates with LYGO RESONANCE engine (falls back to built-in harmonic echo synth).
Ingests or computes Truth × Light (from images via contrast/brightness, or JSON profiles from Glyph2Resonance/FractalWeaver using their truth_light/phi/recursive_harmony fields).
Maps the integral to:
- Harmonic series and intervals (purer with higher truth/light).
- Echo count, recursive delays, and self-similar spacing (echoing the fractal/glyph recursion).
- Decay envelopes and modulations (light quality for brightness/sweep, truth for harmonic stability/richness).
- Evolution: Echoes that build, ring, and recur with increasing/decreasing complexity based on the score.

Outputs:
- Stereo WAV of the harmonic echo sequence (default 30-90s).
- .truthlight.echo.json profile with the integral, echo structure, and LYGO mappings.
- Optional stems (dry + echo layers), MIDI with harmonic echo notes.

Usage examples:
  python truthlightecho.py my_glyph_profile.json --preset pure-light --seed 963 --duration 60
  python truthlightecho.py my_fractal.png --preset truth-echo
  python truthlightecho.py --batch ./profiles/ --preset light-unfold

Ties to LYGO ecosystem:
- Companion to lygo-resonance, lygo-glyph2resonance (#1), lygo-fractalweaver (#2).
- Army-ready (truthlight-echo roles + champions like LYRA, SEPHRAEL, ARKOS).
- Grows to 3-Brain as harmonic truth/light nodes.
- P0/Oath/Guardian aware: local-first, seed-locked, review before external.
