Whether Python code contains at least one complete triple-quoted string
block ("""...""" or '''...'''). code_remove_comments()'s Python branch
deliberately never strips a triple-quoted string as a comment (doing so
would also destroy real docstrings, which are themselves string literals —
see that function's own comment), so a Python file documented ONLY via
docstrings reports 0% comments from code_line_stats() even though it
carries real documentation. This is a separate, additive signal for that
case: it does not change what counts as a "comment" for the existing
percent_comments metric, it only reports whether docstrings are present
at all, alongside it. Confirmed against a real corpus: 200 of 280
zero-comment-flagged Python files (71.4%) contain at least one such block —
see the code_check validation.
