/**
 * macOS-only real-API e2e for plugin-vision.
 *
 * Captures the real screen via `screencapture` (no fixture override) and
 * sends the bytes to a real OpenAI vision model. Skipped on Linux/Windows.
 *
 * Gating:
 *   - ELIZA_REAL_APIS=1
 *   - OPENAI_API_KEY=…
 *   - platform === "darwin"
 *   - macOS Screen Recording permission granted (else skipped)
 *
 * Asserts that a non-empty description comes back from the model.
