The ansi target, txt table styles, kdesc reference from ref/, typeface and table-width fixes (from dev fcec5e2e77ac)

Since the previous release: Machine::read_string() (the fs::path/std::string
overload pair split); kdesc -c and -u rendered from the ref/ reflection
klammerset; a fit column's tex width measured in TeX over every entry;
@typeface resolving to the family its css declares (a store directory name
now works in html) and hieroglyphs in @unicode_examples set in their
typeface; the ansi target -- plain text with the type styles a terminal can
show, identical to txt once the escape sequences are stripped -- with the
txt @table carrying :header_style, :style and :hline; @block anchoring,
@table spacing and the Image_quality state variable; and the rewritten
doc/klammertext_for_llm.md.
