"""测试 Midjourney 代理工具 — Router POST /run_tool

本地服务将 JSON 原样转发至 MIDJOURNEY_API_BASE 上你已实现的三个接口：
  POST /submit_job       cookie, prompt, user_id, mode(relaxed|fast)
  POST /query_job_status cookie, job_id
  POST /get_image_urls   job_id → 四张图链接

用法：
    1. tools/local/midjourney/.env：MIDJOURNEY_API_BASE
    2. uv run python -m tool_agent
    3. uv run python tests/test_midjourney.py

端到端（可选）：设置 MIDJOURNEY_TEST_COOKIE、MIDJOURNEY_TEST_USER_ID 后脚本会
    submit → 轮询 query → get_image_urls；否则仅校验工具已注册并退出 0。

环境变量：
    TOOL_AGENT_ROUTER_URL
    MIDJOURNEY_SUBMIT_TOOL_ID      默认 midjourney_submit_job
    MIDJOURNEY_QUERY_TOOL_ID       默认 midjourney_query_job_status
    MIDJOURNEY_GET_URLS_TOOL_ID    默认 midjourney_get_image_urls
    MIDJOURNEY_TEST_COOKIE / MIDJOURNEY_TEST_USER_ID / MIDJOURNEY_TEST_PROMPT / MIDJOURNEY_TEST_MODE
    MIDJOURNEY_POLL_INTERVAL_S / MIDJOURNEY_POLL_MAX_WAIT_S
