feat: 添加 testTag 基础设施，扩展 Baseline Profile 覆盖路径

为 CalendarPager、BottomCard、FAB、工具页、日期检查器等关键 UI 元素添加 testTag，
启用 testTagsAsResourceId 支持 UI Automator 通过 resource-id 定位。
BaselineProfileGenerator 使用 testTag 选择器重写，覆盖工具页、日期检查器、
DatePicker 等更多导航路径。清理 DEVELOPMENT.md 移除已过时的性能瓶颈描述。

+
 - `MonthView:Compose` — 月视图重组
 - `YearView:Compose` — 年视图重组
 - `YearGridView:*` — 年视图网格组合（首帧耗时关键指标）
 - `generateMiniMonthDays:*` — 月份网格计算
 - `VM:collapseProgress` — 折叠动画
 
-### 已知性能瓶颈
-
-#### AnimatedGif 持续解码
-
-`AnimatedGif` 中的 250×250 WebP 动画在 `repeatCount` 未限制时会以 11-14 FPS 无限循环解码，
-持续消耗 CPU/GPU。已通过 `ImageOptions { repeatCount(2) }` 限制播放 3 次后停止。
-
-#### YearGridView 首帧 168ms
-
-切换到年视图时，`YearGridView` 首次组合需要：
-- 创建 12 个 MiniMonth composable（含 `sharedElement` + `clickable` + `Canvas` 等 modifier 节点）
-- 124 次文本测量（93 日期 + 24 标题 + 7 星期）
-- `SharedTransitionLayout` 注册 12 个共享元素
-
-文本测量已通过 `produceState` 延迟到第二帧执行，首帧 Canvas 渲染为空。
-剩余 ~140ms 是 12 个 composable 节点创建 + layout 的 Compose 运行时开销，
-需要通过 **Baseline Profile** 预编译相关类来优化。
-
-确保 `macrobenchmark` 的 `BaselineProfileGenerator` 覆盖以下路径：
-- 冷启动 → FAB → 年视图（触发 YearGridView 首次组合）
-- 年视图 → 点击任意月份返回月视图（触发 sharedElement 转场）
-
-#### CalendarPager 预加载
-
-`beyondViewportPageCount` 已设为 0，避免翻页时预加载相邻月页导致的帧丢失。
-如需恢复预加载，注意 `compose:lazy:prefetch` 可能产生 400-700ms 卡顿。
