* feat: support system theme auto-switching\n\nAdd 'system' as a third theme option alongside 'light' and 'dark'.\nWhen set to 'system', the UI theme automatically follows the OS\ncolor scheme preference and switches in real-time when the system\nappearance changes.\n\nChanges:\n- useSettingsState.ts: Add resolvedTheme state derived from\n matchMedia('prefers-color-scheme: dark'), add listener for\n system preference changes, update applyThemeTokens to use\n resolvedTheme instead of theme directly\n- SettingsAppearanceTab.tsx: Replace dark mode Toggle with\n 3-segment selector (Light / System / Dark) using Sun/Monitor/Moon\n icons\n- en.ts/zh-CN.ts: Replace darkMode i18n keys with new theme keys\n including 'system' option\n- Default theme changed from 'light' to 'system' for new users\n\nPartially addresses #294
* fix: derive resolvedTheme synchronously and guard matchMedia\n\nAddress Codex review feedback:\n1. Replace resolvedTheme useState+useEffect with synchronous\n derivation from systemPreference state. This eliminates the\n one-frame stale render where useLayoutEffect could apply\n tokens from the old palette before useEffect updated\n resolvedTheme.\n2. Add window.matchMedia guard in the system preference listener\n to prevent crashes in jsdom tests or constrained webviews.\n3. Make the matchMedia listener unconditional (always tracks OS\n preference) to avoid setup/teardown churn when toggling modes.
* fix: resolve 'system' theme in pre-hydration bootstrap to prevent flash
The index.html bootstrap script only handled 'dark'/'light' stored
values. Since DEFAULT_THEME is now 'system', new users (or users who
chose system mode) would get a wrong-theme first paint until React
mounted. Now resolve 'system' via matchMedia('(prefers-color-scheme:
dark)') before applying the CSS class, eliminating the visible flash.
Also use the resolved theme (not raw stored value) for accent foreground
calculation to ensure correct contrast on first paint.
Addresses Codex review on PR #301.
* fix: use resolvedTheme for top-bar toggle to avoid no-op in system mode
When theme preference is 'system' and the OS is dark, the toggle button
showed a moon icon and clicking it just switched from 'system' to 'dark'
— visually a no-op. Now we:
1. Pass resolvedTheme (always 'light'|'dark') to TopTabs for icon display
2. Toggle based on resolvedTheme so the first click always produces a
visible change (e.g. system+dark → light, system+light → dark)

meaningful paint, avoiding initial blank screens or white flashes,
especially on startup and settings windows. Implements a handshake
using a renderer-to-main process message, color-matches background
to the current theme, and falls back to a timeout in development.
