docs: wiki/log 审计修复记录

fix(relay,store): 审计修复 — 自动恢复可达化 + 类型化错误 + 全路径重连
C1: mark_key_429 设 is_active=FALSE，使 select_best_key 自动恢复路径真正可达。之前 429 只设 cooldown_until，恢复代码为死代码。 H1+H2: 重试查询补全 debug 日志（RPM/TPM 跳过、解密失败）+ 修复 fallthrough 错误信息（RateLimited 而非 NotFound）。 H3+H4+M3+M4+M5: agentStore.ts 提取 classifyAgentError() 类型化错误分类，覆盖 502/503/401/403/429/500，统一 createClone/ createFromTemplate/updateClone/deleteClone 错误处理，不再泄露原始错误详情。所有 catch 块添加 log.error。 H5+H6: auth.ts 提取 triggerReconnect() 共享函数，login/loginWithTotp/ restoreSession 三处统一调用。状态检查改为仅 'disconnected' 时触发，避免 connecting/reconnecting 状态下并发 connect。 M1: toggle_key_active(true) 同步清除 cooldown_until，防止管理员激活后 key 仍被 cooldown 过滤不可见。
