/**
 * safe-restart.js — Reinicia o servidor preservando estado do counter e reid
 *
 * 1. Lê count.json e reid/state.json atuais
 * 2. Salva como count-preserved.json e reid-preserved.json
 * 3. Mata processos
 * 4. cv.js escreve fresh-start (normal)
 * 5. counter.py e reid.py verificam preserved → restauram → deletam
 *
 * Uso: node safe-restart.js
