初始提交：terminalX 可运行态（M0/M1/M1.5 已真机验证）

- M0: libghostty SSH 终端（渲染/输入/连接）+ 白屏修复(OutputGate) + 会话状态机/自动重连
- M1: tsnet 用户态组网 + SSH-over-tsnet(fd 桥)，shell 级真机验证；R5(Go+gvisor+C+++Swift 同进程) retire
- M1.5: tmux -CC 原生 tab（MVP）
- 结构: packages/(TXCore·TXTransport), apps/TerminalX, vendor/(libghostty-spm/libssh2/mbedtls/tsnet-bridge), artifacts/
- 文档: CLAUDE.md + docs/HANDOFF.md（新会话入口）
- 环境: 认证代理→依赖 vendor 本地化；Go 在 ~/.local/go；仅模拟器/未签名
- 待续: M2 mosh, tmux 多 pane, M4 安全(host key/SE)

+.SH DESCRIPTION
+\fIsftp\fP - SFTP instance as returned by
+.BR libssh2_sftp_init(3)
+
+\fIsourcefile\fP - Path and name of the existing filesystem entry
+
+\fIsourcefile_len\fP - Length of the path and name of the existing
+filesystem entry
+
+\fIdestfile\fP - Path and name of the target filesystem entry
+
+\fIdestfile_len\fP - Length of the path and name of the target
+filesystem entry
+
+\fIflags\fP -
+Bitmask flags made up of LIBSSH2_SFTP_RENAME_* constants.
+
+Rename a filesystem object on the remote filesystem. The semantics of
+this command typically include the ability to move a filesystem object
+between folders and/or filesystem mounts. If the LIBSSH2_SFTP_RENAME_OVERWRITE
+flag is not set and the destfile entry already exists, the operation
+will fail. Use of the other two flags indicate a preference (but not a
+requirement) for the remote end to perform an atomic rename operation
+and/or using native system calls when possible.
+.SH RETURN VALUE
+Return 0 on success or negative on failure. It returns
+LIBSSH2_ERROR_EAGAIN when it would otherwise block. While
+LIBSSH2_ERROR_EAGAIN is a negative number, it is not really a failure per se.
+.SH ERRORS
+\fILIBSSH2_ERROR_ALLOC\fP - An internal memory allocation call failed.
+
+\fILIBSSH2_ERROR_SOCKET_SEND\fP - Unable to send data on socket.
+
+\fILIBSSH2_ERROR_SOCKET_TIMEOUT\fP -
+
+\fILIBSSH2_ERROR_SFTP_PROTOCOL\fP - An invalid SFTP protocol response was
+received on the socket, or an SFTP operation caused an errorcode to
+be returned by the server.
