perf: 引入 logd 条件日志工具，增强动画调试并优化 sharedElement 缓存

- 新增 AnimLog.kt，提供 BuildConfig.DEBUG 条件控制的 logd 日志工具，
  支持 lambda 延迟求值以避免 release 模式下的字符串拼接开销
- 全模块替换 android.util.Log.d 为 logd，并将日志重构为 lambda 形式
- CalendarViewModel: toggleYearView / selectMonthFromYearView 添加纳秒级
  耗时追踪日志
- CalendarMonthView / CalendarMonthPage / CalendarPager / YearGridView:
  增加重组/进入/离开/页面切换/动画状态变化的详细调试日志
- 折叠动画/滑动进度日志添加状态去重，避免频繁重复输出
- P0: 缓存 sharedElement tween 实例（CalendarMonthView + YearGridView），
  避免每次重组创建新实例导致动画重新计算
- P0: YearPager pageYear 使用 remember 稳定计算，避免 settledPage 与
  yearViewYear 不同步导致抖动
- 移除 YearPager crossFadeAlpha，改为无透明度渐变
- app/build.gradle.kts 添加 profileinstaller 依赖
