T13: Russian hyphenation (hyph-ru through hypher)
T13: Russian hyphenation (hyph-ru through hypher) ## What Text whose language is Russian (`Russian`, `ru`, `ru_RU`) now hyphenates. It uses the same path as Spanish, Portuguese, Norwegian and Greek: the `hypher` crate's `russian` feature, which compiles hyph-utf8's `hyph-ru.tex` (Alexander I. Lebedev, 2003/03/10). The paragraph's limits apply as usual. - `crates/compose/Cargo.toml`: add `"russian"` to hypher's features. `designcraft_doc::language_tag` already maps `russian` → `ru`, so no other code changes are needed. - `crates/compose/src/hyphen/mod.rs`: source note in the module docs, plus the test `russian_uses_the_hyph_ru_patterns`.
