Summary

Resolves #296 — adds a full Russian (ru) localization to Burrow's macOS app, alongside the existing 简体中文 / 繁體中文 tables.

Changes

  • macos/Resources/ru.lproj/Localizable.strings (new): complete Russian translation of all 769 keys, mirroring the canonical zh-Hans key set.
  • macos/Sources/SettingsView.swift: adds Русский to the in-app language picker and updates the "ships English, …" footnote to include Russian.
  • macos/Tests/LocalizationTests.swift: extends the localization suite so Russian is covered for:
    • core-interface key coverage,
    • exact key parity with zh-Hans (no missing/extra keys),
    • format-specifier survival (%, %lld, positional %n$…, etc.).
  • README.md and Store.swift doc comment: list Русский among supported languages.
  • Updated the shipped-languages key in zh-Hans/zh-Hant so the existing Chinese translations keep matching the (now Russian-aware) footnote.

Verification

  • plutil -lint passes on all three .strings tables.
  • A local checker confirmed 769-key parity between ru and zh-Hans and zero format-specifier argument-type drifts across all locales (mirroring the logic in LocalizationTests).
  • No project/build changes are required: ru.lproj is picked up by XcodeGen the same way zh-Hans.lproj/zh-Hant.lproj already are under Resources/.

I was unable to run the full xcodebuild test locally (requires the vendored Sentry/Sparkle frameworks, the burrow-engine submodule, and XcodeGen); CI will exercise the new tests.

Summary by CodeRabbit

  • New Features

    • Added Russian as a selectable app language.
    • Added complete Russian translations across the app, including settings, onboarding, tools, menus, updates, permissions, and AI features.
    • Updated supported-language information in English, Simplified Chinese, and Traditional Chinese.
    • AI explanations now respond in Russian when Russian is selected while preserving required action formatting.
  • Tests

    • Added validation for Russian translation coverage and formatting.

Add a full Russian translation (769 keys) alongside the existing
Simplified and Traditional Chinese tables, and surface Русский in the
in-app language picker.

- new macos/Resources/ru.lproj/Localizable.strings mirroring the
  canonical zh-Hans key set (verified key parity and format-specifier
  integrity)
- SettingsView: add Русский to the language menu and update the
  shipped-languages footnote
- LocalizationTests: cover ru for core-interface keys, key parity with
  zh-Hans, and format-specifier survival

Resolves caezium#296.

clean translation as Очистка, but replace every Purge label and its related
descriptions with a consistent, semantically distinct Russian term throughout
the localization entries.
- Line 271: Update the Russian localization value for the “· latest %ds ago” key
so it includes the measured object and renders as a complete latest-sample
label, such as “· последний замер: %d с назад”, while preserving the existing
format placeholder.

Comment thread macos/Sources/Explain.swift Outdated
Three classes of fix on top of the new ru.lproj table:

- Clean and Purge both rendered as "Очистка", so two different tools
  shared one name in the rail, headers and the "every tool unlocked"
  copy. Purge is now "Глубокая очистка". The Software segment "Uninstall"
  collided with the Installers "Remove" the same way; it is now the noun
  "Удаление".
- Russian agrees the counted noun with the number, and a two-key
  singular/plural scheme can't express that: "%d приложений" is wrong for
  2-4. A .stringsdict wouldn't help either — the String(format:) call
  sites pass no locale, so Foundation applies English plural rules. The
  counted strings are reworded to be count-neutral instead
  ("приложений: %d", "Удалить приложения (%d)", "%d дн.").
- "· latest %ds ago" lost the subject it was counting; it now reads
  "· последний замер: %d с назад".

Explain also answered in English under a Russian UI, because the prompt
language was resolved by a Chinese-only helper. It now resolves ru too.

Both comments described what the code does and left the reasoning out.
replyLanguage() listed its own return values; it now says the reply
tracks the UI language because it renders next to localized chrome.
parse() described the ACTION line's shape without noting that the token
is matched against ExplainSuggestion's raw values, so translating it
would silently drop the suggestion — which is the reason every localized
prompt pins that one line to English.
