docopt.cr 1.5.0

Zero-code colored help: build with -Dcolor_docopt (tartrazine among your dependencies) and an unset colorizer falls back to tartrazine's docopt lexer — terminals only, NO_COLOR respected, explicit colorizer= still wins. A compile-time note suggests -Dnolexers + TT_LEXERS=docopt to link only the docopt lexer. The explicit require "tartrazine/docopt_color" path is unchanged.
