- Skip the three window-manager-dependent E2E assertions (maximize
toggle, main-process state sync, minimize) on Linux CI: GitHub's
ubuntu runners drive Electron under xvfb without a window manager, so
maximize/minimize state never materializes there. Windows CI and
local Linux/macOS runs keep the coverage.
- WINDOW:TOGGLE_MAXIMIZE now returns the requested state instead of
re-reading isMaximized() right after the call, which races on Linux
window managers where maximize()/unmaximize() complete
asynchronously; the WINDOW:STATE_CHANGED push stays authoritative.
- Skip attaching window-state push listeners on macOS, where the
custom controls never mount and the IPC traffic had no subscriber.

Hide the native title bar on win32/linux (titleBarStyle: 'hidden', frame
untouched so native resize borders and snapping keep working) and render
minimize / maximize-restore / close buttons in the renderer, mirroring the
existing macOS traffic-light setup.
- New WINDOW:* IPC contract (minimize, toggle-maximize, close, get-state)
handled in window.events.ts, resolved from the sender WebContents;
close goes through win.close() so window-bounds persistence still runs.
- WINDOW:STATE_CHANGED pushed on maximize/unmaximize/fullscreen so the
maximize/restore glyph stays correct for OS-triggered changes; controls
hide while fullscreen.
- WindowControlsComponent mounts once in app-root as a manual popover so
it stays in the browser top layer above CDK overlays (dialogs,
multi-EPG) - same behavior as macOS traffic lights.
- Theme-aware via CSS vars (--app-on-surface, --app-hover-overlay);
Windows-red close hover. Drag regions get right padding through a
body-level frameless-platform class.
- Gated by RuntimeCapabilitiesService.usesCustomWindowControls; PWA and
macOS never mount the controls.
Includes unit specs for the component and IPC handlers, an Electron E2E
suite (window-controls.e2e.ts), and a window-chrome section in
docs/architecture/workspace-shell.md.
