[Feature Request] add auto benchmark scripts for eigent

[LuoPengcheng12138]

Motivation

hi , @Wendong-Fan We require an automated test script, here is the proposed workflow.:

1. Automatically log in to retrieve the token（for cloud version）
2. Read the benchmark task list (in JSON format)
3. Execute the process for each task
   3.1 Start a chat: Send a POST request to {chat_base}/chat via Server-Sent Events (SSE)
   3.2 Parse SSE events: When encountering to_sub_tasks, send a POST request to /task/{project_id}/start to initiate the task
   3.3 End the current task after receiving the end signal
