perf: 动画性能优化 + 性能追踪工具

- CalendarMonthPage: 提取 WeekRow 子 Composable，graphicsLayer → offset + alpha
- DayCell: updateTransition → 独立 animateFloatAsState/animateColorAsState，
  共享 MutableInteractionSource 减少重组
- CalendarMonthView/WeekPager: graphicsLayer → offset + alpha，共享 interactionSource
- DEVELOPMENT.md: 补充性能追踪使用说明
- scripts/profile.sh: 新增 Perfetto trace 一键抓取脚本

 # 开发指南
 
+## 性能追踪
+
+使用 `scripts/profile.sh` 一键抓取 Perfetto trace、帧统计和内存快照。
+
+```bash
+# 默认抓取 8 秒
+./scripts/profile.sh
+
+# 抓取 15 秒
+./scripts/profile.sh 15
+
+# 应用已在运行时，不自动启动
+./scripts/profile.sh --no-launch
+```
+
+输出文件保存在 `logs/` 目录：
+
+| 文件 | 说明 |
+|------|------|
+| `trace_*.perfetto-trace` | Perfetto trace，在 https://ui.perfetto.dev 打开 |
+| `framestats_*.txt` | GPU 帧统计 |
+| `meminfo_*.txt` | 内存快照 |
+| `report_*.md` | 追踪报告摘要 |
+
+trace 中包含自定义标记：
+- `MonthView:Compose` — 月视图重组
+- `YearView:Compose` — 年视图重组
+- `VM:collapseProgress` — 折叠动画
+- `getMonthDays:*` — 月份网格计算

+| \`trace_${TIMESTAMP}.perfetto-trace\` | Perfetto trace（在 https://ui.perfetto.dev 中打开） |

+| \`meminfo_${TIMESTAMP}.txt\` | 内存快照 |
+| \`report_${TIMESTAMP}.md\` | 本报告 |
+
+## 快速分析指南
+
+### 1. 查看 Compose 渲染耗时
+打开 [Perfetto UI](https://ui.perfetto.dev)，上传 trace 文件，搜索：
+- \`MonthView:Compose\` — 月视图重组耗时
+- \`YearView:Compose\` — 年视图重组耗时
+- \`VM:collapseProgress\` — 折叠动画状态更新
+- \`getMonthDays\` — 月份网格计算
+
+### 2. 分析帧率
+在 \`framestats_${TIMESTAMP}.txt\` 中查看：
+- \`FrameTimeline\` 行 — 每帧的 CPU/GPU 耗时
+- \`jank\` 标记 — 掉帧情况
+
+### 3. 内存分析
+在 \`meminfo_${TIMESTAMP}.txt\` 中关注：
+- \`TOTAL\` 行 — 应用总内存占用
+- \`Graphics\` 行 — GPU 内存使用
+- \`Native Heap\` 行 — 原生堆内存
+
+## 帧统计摘要
+
+- FrameTimeline 条目数: ${FRAME_COUNT}
+- Jank 标记数: ${JANK_COUNT}
