"""Fallback parser — used when no language-specific parser claims the recipe.

Behavior is intentionally minimal. We don't try to extract anything from
arbitrary stdout for unknown (language, recipe) combos — that's a v0.2
problem. All we do is: if the recipe exited non-zero, emit a single
``recipe_fail`` finding so the digest can flag "something went wrong" without
hand-grepping the log. exit_code 0 = no findings.
