feat(app): add global locale coverage

 - Prefer complete translated phrases. Do not concatenate grammatical fragments or make call sites assemble sentences. Keep placeholders to irreducible dynamic values such as names, paths, and counts.
 - If a translation cannot be expressed by the current API, deepen the shared language/UI i18n module so one typed call owns locale selection, plural resolution, fallback, and interpolation. Do not leak that machinery into product code.
 - Do not translate from model knowledge alone. Verify terminology and grammar with Unicode CLDR locale/plural data, Microsoft Localization Style Guides and terminology, Apple localization/style guidance and localized platform UI, Mozilla localization style guides, Mozilla Pontoon, and the Firefox localization corpus at `github.com/mozilla-l10n/firefox-l10n`.
+- For developer-facing terminology, prefer the words already used by the target language's developer community over literal dictionary translations. Cross-check maintained localized developer products such as Firefox, KDE, and VS Code; use at least two independent corpora when they are available. If established practice keeps an English loanword or acronym, keep it rather than inventing a translation.
+- Translate complete UI phrases in context. A glossary hit is evidence, not permission to translate word-by-word. Check terse labels such as session, prompt, agent, model, fork, shell, terminal, workspace, and worktree in the same grammatical role before choosing a term.
+- Before a locale is ready, audit recurring concepts for one consistent translation and review every value that still equals English. Classify retained English as a product name, provider/tool name, URL, code token, keyboard legend, acronym, asset name, or established borrowing; translate unexplained leftovers.
+- In translation review notes, name the corpora used and call out uncertain or region-specific terminology so native speakers can focus review where it matters.
 - Also use the relevant language authority or official dictionary for the locale (for example RAE/Fundéu, FranceTerme, Duden, TDK, Kotus/Kielitoimiston sanakirja, Språkrådet/Bokmålsordboka, Rada Języka Polskiego/PWN, the Russian and Arabic language academies, the Ukrainian Orthography, Taiwan MOE dictionaries, or the Royal Society of Thailand). Treat the English dictionary as the semantic source of truth and preserve placeholders, code identifiers, product names, and keyboard labels.

 - Keep locale and grammar logic in the shared typed i18n layer. Renderer code should resolve copy through the app language API, and the main process should consume typed native-translation bundles through `nativeT(...)`; native menus, dialogs, and IPC handlers must not inspect locales, choose plural categories, or assemble translated sentence fragments.
 - Prefer complete translated phrases with only irreducible dynamic placeholders. If native UI needs richer grammar, deepen the shared bundle/API instead of adding locale branches to desktop feature code.
 - Do not translate from model knowledge alone. Verify terminology and grammar with Unicode CLDR locale/plural data, Microsoft Localization Style Guides and terminology, Apple localization/style guidance and localized platform UI, Mozilla localization style guides, Mozilla Pontoon, and the Firefox localization corpus at `github.com/mozilla-l10n/firefox-l10n`.
+- For developer-facing terminology, prefer established usage in the target language's developer community over literal translations. Cross-check maintained Firefox, KDE, and VS Code localizations, using at least two independent corpora when available. Keep established English loanwords and acronyms instead of inventing unfamiliar terms.
+- Translate whole native-menu and dialog phrases in context. Audit recurring concepts for consistency and review every exact-English value; retain it only when it is an intentional product/provider/tool name, URL, code token, keyboard legend, acronym, asset name, or established borrowing.
+- Record the corpora used and flag uncertain or regional terminology in review notes.
 - Also use the relevant language authority or official dictionary for the locale (for example RAE/Fundéu, FranceTerme, Duden, TDK, Kotus/Kielitoimiston sanakirja, Språkrådet/Bokmålsordboka, Rada Języka Polskiego/PWN, the Russian and Arabic language academies, the Ukrainian Orthography, Taiwan MOE dictionaries, or the Royal Society of Thailand). Treat the English dictionary as the semantic source of truth and preserve placeholders, code identifiers, product names, and keyboard labels.
