Runs in Bulgarian (`w:lang` bg, bg-BG) are hyphenated by the Bulgarian syllable rules
(crates/proof/src/bg.rs, clean-room from the spelling rules; no pattern file or word list):
vowel-vowel splits, one consonant goes with the next syllable, a consonant cluster splits after
its first consonant except that an obstruent before р/л starts the next syllable (до-бре,
та-бли-ца), й stays with its vowel, дж/дз and ьо are never split.
- ProofLang::Bg (bg, bul): hyphenation only. It isn't "proofed", so like Other there are no
spelling or grammar marks until there is a Bulgarian dictionary.
- Latin-script words in a Bulgarian run are hyphenated as English, as in any other language.
- The layout already takes each word's language from its run (ProofRun), so nothing changes there.
Tests: the rules (срич-ко-пре-на-ся-не, та-бли-ца, шо-фьор, хо-джа, строй-ка), tag resolution,
hyphenate_word_in with the paragraph limits (Бъл-га-рия), and a laid-out bg-BG paragraph whose
hyphenated lines all break at Bulgarian points.
