NVC analysis errors during anodization get squelched

When an analysis error occurs during anodization, the error is squelched and we don't get any helpful information back.

Start by tracing the anodization path that invokes NVC and handles the "NVC analysis failed" error, using the displayed command as the reproduction case. Preserve or surface the analyzer's diagnostic output so a failed analysis reports useful details instead of only the summary error.
