Strip all comments from the C# sources

Removes every // and /// comment from the 28 .cs files, -1331 lines.

Done with a lexer rather than a regex: the sources carry plenty of // inside
string literals (@"//\$decor\b", the //$o trainset directives, sb.Append("// "),
"https://wiki.eu07.pl/") and those must survive. It tracks regular, verbatim and
interpolated strings, interpolation holes and char literals. Every file was
checked by comparing the sequence of string-literal characters before and after
the strip; all 28 match. BOMs preserved, blank-line runs collapsed to one.
