Pin Ergonomics contributor steps down, citing LLM fatigue

I'm really sorry to say that I can't continue to finish this goal (at least in the near future). I enjoyed contributing to Rust very much in the past years, until my daily work was extremely overwhelmed by LLM in the past few months. The LLM generates throusands of lines of code every day, but my working time increases and joyness decreases from day to day. I'm too tired to and don't have enough time and energy to contribute here any more. Really sorry for that, and hope I can come back some time.
