test(ci): ANSI-strip help/error asserts in test_v0718 (FORCE_COLOR-robust)

CI (FORCE_COLOR) makes Rich/Typer split flag tokens at colorized hyphens
(--auto-download -> -auto -download) and auto-highlight `=` in error text
(name=path), so contiguous-substring asserts fail. Add the _clean_help helper
(strip ANSI + all whitespace, matching the v0.71.1 / test_v0717 pattern) and
apply it to the sae-diff / train / sleeper / interference --help asserts plus
the bad-adapter-spec name=path error assert. Reproduced + verified with
FORCE_COLOR=1 locally. No source change; test count unchanged.
