fix(i18n): localize Russian desktop tool titles

[DrMaks22]

Summary

• add the missing Russian translations for Desktop assistant tool titles/actions
• localize adjacent thread/clarify labels that were still falling back to English
• keep provider/model/tool identifiers unchanged and preserve the existing defineLocale() structure

Validation

• git diff --check
• python3 /Users/lma/.codex/skills/ru-localization/scripts/lint_ru_quality.py /private/tmp/hermes-pr46634-audit --report /private/tmp/hermes-pr46634-audit-ru-quality.json
  • no findings in apps/desktop/src/i18n/ru.ts; remaining findings are pre-existing in unrelated locales/*.yaml / security docs
• npm run typecheck --workspace apps/desktop
• npm run test:ui --workspace apps/desktop -- src/i18n/languages.test.ts src/i18n/runtime.test.ts src/i18n/context.test.tsx src/components/language-switcher.test.tsx
  • 4 files / 22 tests passed

This is intended as a small follow-up to the already merged wording pass for the canonical RU Desktop branch.

Applied one final QA polish from an independent Russian wording pass: dynamic quoted tool titles now use a colon (Поиск: «query») instead of a looser concatenation.

Re-ran after the update:

• git diff --check
• npm run typecheck --workspace apps/desktop
• npm run test:ui --workspace apps/desktop -- src/i18n/languages.test.ts src/i18n/runtime.test.ts src/i18n/context.test.tsx src/components/language-switcher.test.tsx -> 4 files / 22 tests passed
• RU quality lint: still no findings in apps/desktop/src/i18n/ru.ts; remaining findings are pre-existing outside this PR

Thanks, @DrMaks22 — both commits have now been integrated into feat/i18n-russian-locale via cherry-pick, with the original Git authorship preserved.

The updated branch passes:

• Desktop typecheck
• 4 i18n test files / 22 tests
• git diff --check

The changes are now included in upstream PR NousResearch#46634. Closing this helper PR as integrated. Thank you for the focused QA and Russian wording polish.
