feat(ru): add book locale data (author, format, genre, publisher, ser…

[Nanlung]

Summary
Adds Russian (ru) locale data for the book module so fakerRU.book.* no longer falls back to English.

What’s included

• src/locales/ru/book/
  • author.ts: curated list of Russian(-language) authors
  • format.ts: ['Аудиокнига', 'Электронная книга', 'Твёрдый переплёт', 'Мягкая обложка']
  • genre.ts: Russian equivalents of the EN genres
  • publisher.ts: common Russian publishers
  • series.ts: popular series localized in Russian (e.g., «Песнь Льда и Пламени», «Гарри Поттер», «Дюна»)
  • title.ts: well-known Russian titles (e.g., «Война и мир», «Мастер и Маргарита», «Преступление и наказание»)
• src/locales/ru/index.ts updated via generate:locales

Rationale and data sourcing

• Followed Faker’s “Sourcing data for definitions” guidance: no copyrighted compilations.
• Lists are curated from general knowledge and multiple sources; not copied from a single source.
• Series/titles are provided in Russian where widely used; happy to adjust if the team prefers alternative translations or transliterations.

Validation

• Ran:
  • pnpm run generate:locales
  • pnpm run preflight (format, lint, build, tests, ts-check)
• Snapshots updated as part of preflight; no TypeScript or lint errors.

Notes for reviewers

• Initial, focused set of entries to keep the change reviewable; can expand in follow-ups if desired.
• Open to suggestions on author/publisher/title additions/removals and genre naming consistency.

Checklist

• Locale data added under src/locales/ru/book
• Indices regenerated
• Preflight passed locally
• No breaking changes
