feat(desktop,i18n): Hermes Desktop speaks Russian (#84418, salvage #42705)

[teknium1]

Adds the Russian (ru) locale to Hermes Desktop, closing the gap tracked in #84418: the agent core already ships locales/ru.yaml and the web dashboard has web/src/i18n/ru.ts, but the desktop app only offered en/zh/zh-hant/ja/ar.

Credit

This is a salvage PR consolidating a 7-PR duplicate cluster:

• 🥇 @warment filed the earliest request-plus-implementation in feat(i18n/desktop): add Russian (ru) locale #42705 (Jun 9) — first to bring desktop Russian to the table. Their branch had grown a +4298/−260 diff across ~35 unrelated .tsx files against current main, so it couldn't be cherry-picked cleanly.
• 🛠️ @FASTCHIP's implementation from feat(desktop): add Russian (ru) locale #91780 (Aug 21) was the cleanest, most current, and most complete catalog — it is cherry-picked here with original authorship preserved in git history.

Duplicate PRs superseded by this one (left open for maintainer disposition, not closed by this PR): #42705, #66833 (@timoncool), #70499 (@Gromakoff), #70673 (@saimon4eg), #78483 (@konstantin969696), #91780 (@FASTCHIP), #92096 (@systemINTERNET). Thanks to all of you — seven independent submissions is a strong signal this was wanted.

Related but separate scope (dashboard web/ ru completion, NOT included here): #88444, #97969.

Why #91780 as the base

• Narrow 4-file footprint touching exactly the i18n seam (ru.ts, languages.ts, types.ts, catalog.ts); only 3 lines of deletions.
• Largest/most current catalog of the cluster (3,662 lines vs ~2,900 in the July PRs), tracking a much newer en.ts.
• Follows the current conventions exactly: defineLocale() partial catalog with English fallback, defineFieldCopy() for settings field labels/descriptions (the ja/zh-hant pattern — no separate ru-constants.ts file like older entries used), and proper Russian plural forms via RU_PLURAL/RU_NOUN helpers (one/few/many).
• Only one trivial conflict on cherry-pick (types.ts Locale union vs. the newer TipId import), vs. 9,000–10,000+ commits of staleness on the July entries.

What's in the follow-up commit

• Translated the handful of leftover untranslated "toolset(s)" strings in ru.ts into natural Russian («набор инструментов»).
• languages.test.ts: ru alias/isLocale/localeConfigValue coverage, mirroring exactly how ar (the most recently added locale, 5b6990e) was wired. No context.tsx changes needed — Russian is LTR, so the RTL plumbing from the ar commit doesn't apply.
• website/docs/user-guide/desktop.md: the UI language switcher bullet now lists all six desktop locales including Russian.

Wiring checklist (mirrors the ar locale commit's touchpoints)

• types.ts — 'ru' in the Locale union
• catalog.ts — ru imported and registered in TRANSLATIONS
• languages.ts — LOCALE_OPTIONS entry (endonym Русский, englishName Russian) + aliases ru, ru-ru, ru_ru, ru-by, ru-kz, russian, русский (incl. common misspelling руский)
• languages.test.ts — alias/id/config-value coverage
• Docs updated in the same PR
• defineLocale() partial → any key added to en.ts later falls back to English cleanly (verified: parity probe shows fallback handles the delta; tsc --build clean)

Verification

• npx vitest run src/i18n/ → 4 files, 28 tests passed
• npx tsc --build tsconfig.json → clean
• npx eslint on all touched i18n files → clean
• python3 scripts/audit_pr_attribution.py → all contributor emails mapped (FASTCHIP uses an id+login@users.noreply address; CI auto-resolves)
• Translation spot-check: natural Russian with correct ё usage, «…» quoting, and grammatical plural forms

Closes #84418.
