feat: spectral threshold tuning + Gremlin-to-AppFloyo push

Spectral thresholds:
- Lower signalThreshold from 2.0 to 1.5 (98304 Q16_16 raw)
- colorToShapeName now returns LogogramProjection for blue-only
  (was none, which caused missing_prediction alignment status)
- Result: 0 missing_prediction, 32 aligned_exact, 66 compatible,
  180 alignment_warning across 278 rows

Gremlin bridge:
- Added push_to_appflowy() with auto GoTrue JWT acquisition
- PUSH_APPFLOWY=1 env var triggers push after report generation
- Retained JSON/Markdown file output as primary delivery
