v0.22.2

改进：「最近失败」能认出"被服务商拦截"：WorkBuddy 国际版的「请求被拦截」、国内版的 11-128（未经批准的渠道）。会写明原因：服务商在限制官方客户端之外的使用，请改用其他来源或建组合，继续调用有封号风险。组合切换遇到这种拦截也会换下一个模型。

Change: recent failures now recognise "blocked by the provider" (WorkBuddy AI's 请求被拦截, WorkBuddy China's 11-128 unapproved channel) and say why: the provider is restricting use outside its app, so switch source or use a combo; continuing risks the account. Combos move on past this error too.
