Bug Fixes / 修复

• Fix rsync transport on Windows — overlapped stdin handle — when rsync (MSYS2, Cygwin, or cwRsync) forks flyssh as the -e transport, the inherited stdin pipe is opened for overlapped (async) I/O. Go's os.Stdin.Read calls ReadFile with a nil OVERLAPPED pointer, which is invalid for async handles (Windows error 87 "The parameter is incorrect"). A new rawStdinReader() reads via the Windows ReadFile API with a proper OVERLAPPED struct, fixing the root cause (Go issue #15388) / 修复 Windows 上 rsync 传输失败：rsync（MSYS2/Cygwin/cwRsync）fork flyssh 作为 -e 传输时，stdin pipe 被设为 overlapped I/O 模式，Go 的 os.Stdin.Read 传 nil OVERLAPPED 导致 error 87。新增 rawStdinReader() 使用带 OVERLAPPED 结构体的 ReadFile 调用修复此问题

Improvements / 改进

• Improved Windows rsync detection — rsync is now searched in: (1) flyssh.exe directory, (2) current working directory, (3) %PATH%, (4) well-known MSYS2/Cygwin/cwRsync/ICW paths. When not found, actionable install instructions are printed / Windows rsync 检测增强：依次从 flyssh.exe 同目录、当前工作目录、%PATH%、已知安装路径查找 rsync，未找到时输出安装指引

Docs / 文档

• Windows rsync prerequisites documented — README now includes a dedicated section on Windows rsync setup, explaining the overlapped I/O limitation and supported rsync sources / README 新增 Windows rsync 前置条件章节，说明 overlapped I/O 限制及支持的 rsync 来源

Verification / 验证

• go build ./...
• GOOS=windows go build ./...
• go test ./...
• Live Windows test: 57 MB rsync upload with Chinese-character paths succeeded (MSYS2 rsync + Cygwin rsync)
