integrate: erans field effect spectrum into master synthesis

Browse source 
Evolve erans from flat histogram coding to spectral decomposition
of residual field (field effect spectrum).

Changes to master synthesis:
- Added erans_field_effect_spectrum to theoretical_foundations
- Updated stage_13: compute residual correlation matrix C,
  eigen-decompose C = UΛU^T, code spectral coefficients with erans
- Updated source to include erans-field-effect-spectrum
- Added 3 new compression gain sources:
  * erans_spectral_compaction (10-20% gain from energy compaction)
  * spectral_pattern_separation (2-3% gain from spectral overlap)
  * famm_spectral_pruning (3-5% gain from residual spectral energy)
- Updated estimated aggregate gain: 20-35% reduction (was 18-28%)
- Added 6 spectral keeper phrases
- Updated core_synthesis to mention spectral decomposition
- Added 5 new tags: erans-field-effect, spectral-encoding,
  residual-field-spectrum, field-effect

Field effect spectrum: residual correlation matrix C captures how
residuals propagate through manifold. Spectral energy compaction
(90% energy in 10% coefficients) provides 10-20% gain over flat
histogram coding. Spectral overlap measure improves OAC gate precision.
FAMM delays use residual spectral energy for context efficiency.
