Byte-level comment stripping with Stage-0 parity: "--" begins a comment
only at token start (a dash inside an identifier is name material), and a
comment runs to the end of its line. States: 0 between tokens, 1 inside
an atom, 2 pending single dash, 3 inside a comment. Each byte reduces to
one emitted byte string plus one next state so the fold recurses exactly
once per byte.
