Review (#1312 rewrote crates/text/build.rs): the family list is read in
main() and passed to input_fonts and craft_fonts the way embed_cjk is;
the families nothing embedded come from the catalog's faces, not from
searching the generated source; a fixture test covers the web catalog
with and without the list, native builds and that check; and
docs/releasing.md no longer says the release pin lacks Noto Sans Thai
(37827adc has it). The warning now also says when no craft-fonts
manifest was read.
