Turns a drained pipe into lines the way callers already expect.

<p>tmux emits pane content, so the bytes are not guaranteed to be UTF-8. A malformed byte is
escaped as {@code \xNN} rather than replaced with U+FFFD, which keeps the original byte
recoverable and matches what CPython's {@code backslashreplace} produces.

<p>The two channels split differently: stdout keeps interior blank lines and drops only trailing
ones, stderr drops every blank wherever it appears. That asymmetry is not a tidy rule, it is the
observable shape callers depend on.
