Usage:
  ./local/scripts/test-phase2-runtime.sh --guest
  ./local/scripts/test-phase2-runtime.sh --qemu [redbear-full]

This script validates the Phase 2 Wayland compositor proof by running the
canonical Phase 2 check binary and treating its exit code as authoritative.

Required binary (must be in PATH inside the guest):
  redbear-phase2-wayland-check — Wayland compositor proof validation
