Why

The interface is in six languages since 1.6.2, but the README and the guide are only in English and Portuguese. Someone who finds the project on a German or Russian forum lands on a page they may not read, and there was no written path for people who want to help translate (the German translation came from a Reddit user on their own).

What

• README.<code>.md and docs/GUIDE.<code>.md for es-ES, de-DE, fr-FR and ru-RU.
  • The READMEs are leaner on purpose: no version number (they link to releases/latest), no "What's new" and no roadmap, so a release doesn't require touching four more files. They point to CHANGELOG.en-US.md for news.
  • The guides translate every section except "Build from source", which links to the English one.
  • UI labels are taken from each language's Strings.<code>.json, so the docs say exactly what the app shows (e.g. „Zurück zum PC“, « Revenir au PC », «Вернуться к ПК»). Labels from Android TV settings, which the app doesn't have, use the usual local name with the English in parentheses where unsure.
  • Each translated page ends with a note that the English version wins if they differ.
• Language bar on top of all 12 pages (replaces the old "🇧🇷 Leia em português" / "🇺🇸 Read in English" links).
• docs/TRANSLATING.md (English): how to fix a line, how to add a language (the JSON, plus the six wiring steps: csproj ×2, LocalizationService, the test row, the installer, README/changelog, TESTING.md), style rules (placeholders, short text for the TV, tone, official names) and how to run the checks without Windows. Linked from "More" in the README in every language.
• AGENTS.md: the catalogs rule listed three languages; it now lists all six and mentions the translated docs.

The guide mentions the "sentence left in English" check from #156, so this one reads best merged after it.

No changelog entry: nothing changes in the app.

Testing

• All local links and #anchors across the 12 pages and TRANSLATING.md checked with a script (GitHub slug rules, Cyrillic and accented headings included): 0 broken.
• Docs only; no code touched. The Windows build is left to CI.
