 - [x] **新增: 每聊天图片处理上限** — `MAX_IMAGES_PER_CHAT = 30`，防止单个高活跃群聊垄断处理时间（30张×10s = 5分钟/聊天）

+- [x] **修复: UNKNOWN 状态长时间无法恢复** — 原恢复逻辑只做 activate + 点侧边栏，遇到弹窗/多余窗口无法清理。改为先 Escape + Cmd+W 关闭可能的弹窗，再 activate + 点侧边栏
+- [x] **改进: 恢复失败指数退避** — 外层循环连续恢复失败时退避等待：10s → 20s → 40s → 80s → 120s（封顶），避免每 13 秒重复无效尝试。恢复成功后计数器归零
