except RuntimeError as exc:

Catch all chart generation failures in multi-analyze

The multi-analyze flow only catches RuntimeError when generating charts, so common I/O failures from savefig (for example an unwritable --charts-dir or invalid output filenames) will propagate and terminate the command even though the analysis result is already available. This makes charting an all-or-nothing step instead of the intended best-effort behavior already used for missing matplotlib.

Sanitize column names before composing chart filenames

Chart output paths interpolate raw CSV column names directly into filenames, so headers containing path separators or filesystem-reserved characters (e.g. a/b, x:y) produce invalid or unintended nested paths and cause fig.savefig to fail. Because column names come from input data, this can break chart generation for otherwise valid CSV files.
