Levi Neuwirth f77ff3074d test(vterm): write CRLF from the raw-mode probe 
The diagnostic added in the previous commit answered the question on its
first macOS run:

    rendered prefix: 6/15 bytes ("VTERM_") — child text rendered only partially

So the child wrote and the host received part of the marker, but stripping
escapes did not rejoin the rest: other repainted cells sit between the two
pieces, not just cursor moves.

Six characters is exactly what fits before the right margin of this
session's 40-column child. The probe writes bare `\n`, and the supervisor's
PTY trampoline runs `stty raw`, which clears OPOST — so a lone `\n` moves
down without returning to column 1 and every line staircases five columns
right. After twenty lines the marker starts in the right margin, wraps
mid-word, and reaches the host as two pieces that no contiguous match can
join.

That also explains the intermittency: the wrap column depends on whether
pmacs has already resized the PTY from the requested 40 columns to the
window width, which races the child's first writes.

Write explicit carriage returns so every line returns to column 1 and the
markers start there. The fixture was wrong about its own line discipline;
the emulator was behaving correctly throughout.

The escape-stripped matching and the rendered-prefix diagnostic from the
previous commit are kept: they are what produced this answer, and they keep
the next such failure legible.

Test-only; no runtime code.
