feat: /status 通用状态显示 + /compact 手动压缩；HTML 兼容渲染默认化

- /status：绑定会话/会话 ID/工作区/当前模型/思考强度/上下文长度/
  首 token 平均/输出速率/输入输出 tokens —— 与 Web 底部统计条同源
  同算法（sessionProjections: sessionStats/tokenUsage/contextPressure），
  投影插件缺失时逐组优雅降级；冷会话不强制 resume
- /compact：复用 ctx.compaction.compactNow 手动压缩绑定会话历史，
  异步执行不阻塞轮询，完成/失败均中文通知，同会话去重，
  桥停止/热重载自动中止进行中的压缩
- 全部用户可见文案不使用 emoji
- rendering 默认改 html（兼容优先）+ userQuestions/approval 双通道等
  既有修改一并合入（此前已上线确认）
- tests：+6 覆盖 /status 全字段与 /compact 各分支（51 全绿）
