862992ec98 fix: regenerate PIST predictions pipeline, fix Matrices250 kernel blowup
- generate_predictions.py: reads 278 equations from classifier receipt,
  builds 8×8 strand adjacency matrices, deduplicates to 250 by equation_id
- build_pist_matrices_250.py: emit each matrix as a separate Lean def
  (match-based findMatrix) to avoid kernel term-size blowup
- rrc_pist_predictions_250_v1.json regenerated in Research Stack shared-data/
- Shakeout finding: text-derived matrices have spectral radius < 2.0,
  so classifyExact returns none (expected — 250 non-zero matrices, weak features)
