[susu] 读取按钮详情失败

Error message

[susu] 读取按钮详情失败: %w

What it means

Reading the (2MB-capped) susu button-detail response body failed mid-stream after a 200: connection reset, read timeout, or truncation by an intermediary. The status check already passed; only the body transfer broke.

Solutions

1. Retry the button-detail request
2. Keep the LimitReader cap to avoid unbounded reads
3. Check for proxies truncating responses
