fix: resolve punycode to userland package and skip env var test in sandbox

- Resolve punycode to userland package instead of deprecated node:punycode
  built-in to avoid deprecation warnings
- Skip cron-tools env var test in sandbox mode since Docker containers
  don't receive environment variables set in the test process
