// Local terminal streams for the client, per runtime.
//
//   - node: process.stdin/stdout/stderr are already TTY streams (setRawMode,
//     columns/rows, 'resize') — use them directly.
//   - bare: bare's process stdio isn't raw-mode capable; construct bare-tty
//     ReadStream/WriteStream on fds 0/1/2, which expose the same TTY surface
//     (setRawMode, columns/rows, 'resize') that ShellClient relies on.
//
// `#node:tty` maps to bare-tty on bare and node's tty on node; we only touch it
// on the bare branch.
