FormatCommandLine wrote option and value arguments using the ambient thread culture via value.ToString(), while the parser reads them back with ParserSettings.ParsingCulture (invariant by default). On threads whose culture uses a comma decimal separator (for example de-DE) a double 1.5 was unparsed as "1,5" and reparsed as 15, and a sequence [1.5, 2.5] became "1,5,2,5" and reparsed as four elements [1,5,2,5], so the format/parse round-trip was broken. Format IFormattable values (numeric and date/time types) with the parser ParsingCulture instead of the current thread culture, for both scalar and separator-joined sequence values. Other types keep their default string representation, so behaviour on invariant/en-US is unchanged. Add round-trip tests under de-DE for a scalar double and a comma-separated double sequence.
