🇷🇺 Русский reference data

Fully supported — read, tap-to-define, mine vocabulary, and practice frequency-banded cloze in Russian: the first Cyrillic language pack. The on-device dictionary covers Russian's rich inflection (six cases, verb aspect pairs, suppletive forms like шёл → идти), understands the everyday е-for-ё spelling (теплое finds тёплый), and shows lexical stress in definitions.
