Previously, Cmd+W on the last surface kept the workspace alive with a
replacement shell, unless the user toggled a hidden setting. This was
confusing—users expect Cmd+W to close the window when there's nothing
left.
Now Cmd+W (and the tab-strip X button) always close the workspace when
they close its last surface, and close the window when that was the last
workspace. Internal/programmatic closes (e.g. process exit, panel moves)
still spawn a replacement shell so the workspace stays alive.
Key changes:
- Track explicit user close gestures via markExplicitClose / onTabCloseRequest
- Remove the LastSurfaceCloseShortcutSettings toggle (now always-on)
- Use window.performClose for last-workspace window close
- Update tests to match the new behavior

Snapshot TabManager's published state (tabs, selectedTabId) at the start
of workspace creation so mutations don't bounce through Combine-backed
accessors mid-creation. Prevents crashes when adding a workspace via
Cmd+N, the new-workspace button, or any other creation path that
triggers re-entrant publishes.

Add accessibilityAddTraits(.isSelected) to Theme and App Icon picker
buttons so VoiceOver announces the active option. Reorder the top of
the App section to: Language, Theme, App Icon.

* Add subtitle to App Icon setting to reduce confusion with theme
Users were confusing the App Icon picker (Automatic/Light/Dark) with
the Theme toggle. Add "Dock and app switcher" subtitle to clarify
this setting only affects the icon appearance, not the app theme.

* Replace Theme dropdown with visual appearance picker
Draw window thumbnails showing light/dark previews with traffic light
dots and content bars, matching the macOS System Settings appearance
picker pattern. System mode shows overlapping light+dark thumbnails.

* Swap theme picker to Gemini's wallpaper + layered window design
Replace flat single-window thumbnails with richer previews: wallpaper
gradient backgrounds, menu bar with Apple logo, two layered windows
with shadows, and a split-mask for the System option (light on left,
dark on right with center divider), matching the macOS System Settings
appearance picker more closely.

* Move Theme and App Icon pickers to right-aligned row layout
Both pickers now use an HStack with the label on the left and
thumbnails on the right, matching the SettingsCardRow pattern.
Thumbnails get layoutPriority(1) so the label text compresses
first on narrow windows. Slightly smaller thumbnails (76x50 for
theme, 48px icons) to fit comfortably at minimum settings width.

* Top-align labels in Theme and App Icon picker rows

* Increase hitbox on picker buttons and remove focus ring
Add contentShape(Rectangle()) for full-area tap targets, increase
padding (8v/10h), and add focusable(false) to prevent the macOS
keyboard focus outline from showing on the buttons.

* Use rounder squircle corners on theme thumbnails
Bump cornerRadius from 10 to 14 on the thumbnail clip shape and
border for a more pronounced squircle look.

* Use true superellipse squircle shape for theme thumbnails
Add a Squircle shape that draws a superellipse (n=4) path blended
with an ellipse based on corner radius. Apply it to the theme
thumbnail clip and border instead of RoundedRectangle.

* Remove custom Squircle struct, use built-in continuous rounded rect
RoundedRectangle(style: .continuous) is Apple's squircle. The custom
superellipse shape was unnecessary.
