feat: add max_wait_time parameter to job_output tool

[heimoshuiyu]

Allow job_output tool to wait for job completion with configurable timeout. The tool now supports a max_wait_time parameter that enables monitoring long-running tasks without continuous polling. When the timeout is reached, it provides helpful feedback suggesting a longer wait time.

• [x] I have read CONTRIBUTING.md.
• [ ] I have created a discussion that was approved by a maintainer (for new features).

This should not be considered a feature, but rather a fix. It prevents the crush from repeatedly calling job_output within a short period to check if the task is completed.

In YOLO mode, the crush sent over 20 requests in one minute to check if the compilation task was finished, and the repeated tool calls quickly exceeded the model's context limit. This is a serious issue.

Adding a maximum wait time parameter can resolve this problem.
