Multi-value (nargs="+") options were only comma-split for non-str types because the neutralization gate skipped str-typed arguments. Passing a list of paths through the Python API, e.g. rtk.rtkcheckimagequality(reference=["a.nrrd","b.nrrd"]), serialized as a single comma token but was never split, yielding one bogus filename "a.nrrd,b.nrrd". Neutralize the type of every nargs="+" option, including str/path lists, then split comma tokens and re-cast each piece (str cast is a no-op).
