The always-visible row subtitle remains English under zh-CN (for example, Connected, Offline, and Connection failed), so the primary connection-status UI is not localized. subtitleText uses the hard-coded status.text from savedBackendStatus, while connectionStatusCopy is only passed to the hover tooltip; use the localized status text for this subtitle as well.

formatUpcomingTimestamp returns usage-limit reset timestamps in the host locale and emits English tomorrow at for zh-CN, so these timestamps remain untranslated while day-aware chat timestamps are localized. Add a language parameter, pass it to the time and numeric date formatters, and use the localized tomorrow label (updating callers to provide the persisted language).

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This change adds a persisted system-selected language preference and a cross-cutting i18n layer that changes default UI behavior across many production surfaces. Visible connection-status and usage-reset paths also remain partially unlocalized, increasing the need to verify the complete user experience. Not approved because:

Suggested reviewers: Merge Risk: 🟡 Moderate · up to This change adds Simplified Chinese support across most of the web UI, but several visible areas—parts of the diff viewer's ref-search dropdown, the composer's disconnected placeholder, and certain composer action labels—still show untranslated English text when Chinese is selected, along with a few smaller localization and formatting gaps in settings and connection status. None of these break core functionality, but the localization feature is not fully complete, so review before merging or plan a fast follow-up to finish translating the remaining strings. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

Use an English locale for the English formatter.
undefined uses the browser locale, not the selected en language. A user who selects English with a zh-CN browser locale still gets Chinese date formatting. Set this formatter locale to "en".

Translate the language search-result title.
With zh-CN selected, a search for 语言 returns this entry but displays the static English title "Language". Store a message key for searchable titles and render it through t, or localize this entry through an equivalent catalog contract. Update the assertion in apps/web/src/components/settings/settingsSearch.test.ts to cover the translated result.

Pass the selected language to formatUpcomingTimestamp.
UsageLimitsPooled.tsx and UsageLimits.tsx call this helper. It formats time and numeric dates without AppLanguage, and its next-day branch returns hard-coded "tomorrow at ...". A zh-CN UI can therefore show English text and host-locale dates. Add language?: AppLanguage, localize the next-day label, pass the language to both formatter calls, and update both callers.
