Code Review

This pull request refactors the ConnectionStatusIndicator to read navigator.onLine dynamically on every render and simplifies internationalization by calling useI18n directly inside the memoized body component. It also updates the disconnect handler in sync-context.tsx to transition to a reconnecting or connecting phase. However, unconditionally setting these phases can mask terminal errors like authentication failures; it is recommended to check for auth failures and preserve the "disconnected" phase when manual intervention is required.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
