[vaur94]

Issue for this PR

Closes # N/A — Turkish locale was missing from packages/app and packages/ui while already present in packages/console and packages/web.

Type of change

• Bug fix
• New feature
• Refactor / code improvement
• Documentation

What does this PR do?

Adds Turkish (Türkçe) locale to the app and shared UI packages. Turkish was already supported in packages/console (tr.ts) and packages/web (tr.json) but was missing from the two packages that power the desktop app and web interface.

Changes:

• packages/app/src/i18n/tr.ts — Full Turkish translation of all 825+ app keys
• packages/ui/src/i18n/tr.ts — Full Turkish translation of all 118 UI component keys
• packages/app/src/context/language.tsx — Registers tr in the Locale type, LOCALES array, LABEL_KEY map, DICT merged dictionary, localeMatchers, and PARITY_CHECK
• packages/app/src/i18n/en.ts — Adds "language.tr": "Türkçe" to the base English dictionary
• packages/app/src/i18n/parity.test.ts — Includes tr in the parity test suite

How did you verify your code works?

• Parity test passes: bun test src/i18n/parity.test.ts → 1 pass, 0 fail, 64 expect() calls
• TypeScript type check passes with no errors in tr.ts or language.tsx
• Vite build succeeds

Screenshots / recordings

N/A — i18n string additions only, no UI layout changes.

• Add new Turkish translation dictionaries for packages/app and packages/ui
• Register tr in the app language context (types, locale list, labels, merged dictionaries, matchers, parity check)
• Extend base English dictionary and parity test coverage to include Turkish

packages/ui/src/i18n/tr.ts:6

• Turkish translation here drops required diacritics (e.g. "degisiklikleri"). The UI uses full Unicode in other locales, and this PR already includes "Türkçe", so it should be safe to use proper Turkish spelling ("değişiklikleri").

  "ui.sessionReview.title": "Oturum degisiklikleri",

packages/ui/src/i18n/tr.ts:40

• Spelling issue in Turkish string: "planlanyor" is a typo. This should be corrected (and ideally use Turkish diacritics consistently).

  "ui.sessionTurn.status.planning": "Sonraki adimlar planlanyor",

packages/ui/src/i18n/tr.ts:122

• Typo in placeholder text: "Cevabnizi" is missing a character. Please fix the spelling (and consider using proper Turkish casing/diacritics).

  "ui.question.custom.placeholder": "Cevabnizi yazin...",

packages/app/src/i18n/tr.ts:53

• Typo in Turkish translation: "bagalama" should be "baglama" (extra 'a'). This impacts the UI label shown for adding a selection to context.

  "command.context.addSelection": "Secimi bagalama ekle",
  "command.context.addSelection.description": "Mevcut dosyadan secili satirlari ekle",

packages/app/src/i18n/tr.ts:518

• Same typo as earlier: "bagalama" should be "baglama" (extra 'a'). Please keep these labels consistent across the dictionary.

  "session.context.addToContext": "{{selection}} bagalama ekle",
  "session.todo.title": "Gorevler",

packages/app/src/i18n/tr.ts:816

• Typo in Turkish translation: "eslesyor" is missing a letter (should be "eslesiyor").

  "workspace.reset.success.description": "Calisma alani artik varsayilan dalla eslesyor.",
  "workspace.error.stillPreparing": "Calisma alani hala hazirlaniyor",
