feat(timer): 循环训练组进度改为圆环分段弧 + 信息气泡三行合一

- progress-ring 新增 sets/currentSet/resting/successColor 属性,
  圆环外圈绘制分段弧(已完成=主色/当前=呼吸光点/休息下一组=绿),单组模式零渲染
- timer 删除顶部 circuit-bar 进度面板,布局骨架三模式统一
- 呼吸环淡化(描边 0.55→0.20,柔光渐变强度减半)
- 目标卡与提示气泡合并为 info-bubble,状态文案(撑住/休息中/已暂停)并入气泡顶部

+//  2) 独立 console 语句整行删除（含无分号情况）
+//  3) 收敛多余空行（>=3 个连续换行压成 2 个）
+// 删除后由调用方逐个 node --check 验证语法。
