fix(profile.sh): 修复帧率和内存数据提取逻辑

- Janky frames 百分比：grep -oP 替换为 BSD awk 兼容的 substr+index
- Slow UI thread / Slow draw commands / High input latency：改用 $NF 提取最后一个字段，
  避免 "Slow UI thread" 等中间空格导致 awk 列错位
- Java Heap / Native Heap：改用 $3 提取，避免 "Java Heap:" 中 $2 是 "Heap:" 而非数值
- 所有指标改用 awk + exit 取第一个匹配（整体统计），避免 tail -1 取到 per-window 数据
