feat: AOT 单文件静态链接 + Release 引导脚本

- csproj 静态链接 Skia/HarfBuzz/ANGLE（CoreUtils.*.Static），AOT 产出真单文件
- 发布后清理 .dll/.lib/.pdb，只留 notify.exe
- bin/notify.cmd 与 notify.sh：首次运行从 Release 下载 notify.exe
  原子下载（临时文件+改名）+ mkdir 锁，并发不重复下载，带陈旧锁恢复
- 修复 cmd 引导脚本管道 stdin 丢失：避免调 exe 前向前 goto，改用 call 子程序
- hooks.json 指向 notify.cmd，超时放宽以容纳首次下载
- .gitignore 放行两个脚本但忽略 notify.exe；.gitattributes 固定脚本换行符
