No issue. The problem is described below.

Problem

The desktop app downloads an update in the background and then never tells the user it is ready, so the new version only takes effect on a manual restart. The sidebar header also had two smaller issues: the settings button sat off centre in the footer, and the brand was inert.

What changed

  • A desktop-only update toast that appears when an update is ready and offers install or skip.
  • A matching control in the settings pane.
  • The sidebar footer settings button is centred, and the sidebar brand starts a new session.

The toast renders only under the desktop shell, so the browser build is unchanged.

  • I have linked a related issue, or explained the problem above.
  • I have added tests that prove my feature works.

Summary by CodeRabbit

  • New Features
    • Added desktop update notifications with download, restart-to-install, and version-specific skip options.
    • Clicking the sidebar brand now starts a new session.
    • Added a close button to the settings pane.
    • Improved settings navigation and Windows title-bar styling.
  • Localization
    • Added English translations for update prompts and settings controls.
  • Bug Fixes
    • Update prompts now persist skipped versions and appear for newer releases.

Add a desktop-only update toast that offers install or skip, centre the
settings button in the sidebar footer, and make the sidebar brand start a
new session.

Desktop update toast

The application displays localized update actions, supports download and restart installation, persists skipped versions, and tests updater states and actions.
Settings pane close flow
apps/pythinker-web/src/components/settings/SettingsPane.vue, apps/pythinker-web/src/i18n/locales/en/settings.ts, apps/pythinker-web/src/App.vue
The settings pane emits a localized close event, and the application hides the settings view when it receives the event. Windows title-bar styling is also updated.
Sidebar navigation and layout
apps/pythinker-web/src/components/Sidebar.vue, apps/pythinker-web/test/sidebar.test.ts
The sidebar brand emits create when clicked. Settings controls use centered card styling, dimmed back styling, and keyboard focus styling.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 73a2b

This PR adds a desktop update prompt and sidebar interactions. A runtime initialization-order bug prevents skipped update versions from being restored, so users may be prompted again after remounting or restarting; that correctness issue should be fixed before merge. The brand button also lacks an accessible action name and the settings back control misses its intended hover color as bounded follow-ups.

Add an accessible name for the brand button.

The button's accessible name is currently Pythinker Code, while its action is to create a new session. The title attribute does not replace the button's content name. Add the localized action label.

Proposed fix
         <button
           type="button"
           class="ch-brand"
           :title="t('sidebar.newSession')"

           `@click.stop`="emit('create')"

Restore the hover color for the settings-mode back control.

.settings-row:not(.end) has higher specificity than .settings-row:hover. Therefore, the generic hover rule cannot change the back control color to var(--ink), despite the comment stating that the control becomes brighter on hover.

Proposed fix
 .settings-row:not(.end) {
   color: color-mix(in srgb, var(--muted) 65%, transparent);
   font-weight: 400;
 }
+.settings-row:not(.end):hover {

Initialize SKIP_KEY before reading persisted skips.

Line 15 calls readSkipped() before Line 16 initializes SKIP_KEY. The temporal-dead-zone error is caught, so every component mount starts with an empty skipped-version list. Move SKIP_KEY before skipped so skipped versions remain hidden after a remount or restart.

Proposed fix
+const SKIP_KEY = 'pythinker.update.skipped';
 const skipped = ref<string[]>(readSkipped());
-const SKIP_KEY = 'pythinker.update.skipped';

Based on learnings: "readSkipped() catches errors when SKIP_KEY is accessed before initialization" and this order prevents persisted skipped versions from loading.
