chore: add start/stop/restart scripts for Planarchy

- scripts/start.sh: docker compose up, prisma generate, clear .next cache,
  start Next.js, wait for health check, show status
- scripts/stop.sh: kill Next.js by PID + fuser, docker compose stop
- scripts/restart.sh: stop then start

Usage:
  ./scripts/start.sh    # Start everything
  ./scripts/stop.sh     # Stop everything
  ./scripts/restart.sh  # Full restart
