Redesigns Monolith's existing Library/Favorites, Collections and Settings using the supplied screenshots as the visual reference.

• Adds the compact icon rail, status/capture bar, full-width library toolbar, five-column desktop clip grid and folder-style collections.
• Moves Settings into a full page with secondary navigation, page search and divided settings cards.
• Uses native Preact shadcn-style Button variants, official GLOW SVG icons and bundled Inter. Asset licenses are included in the production bundle.
• Connects title-bar clip/start/stop controls to existing recorder commands, refreshes configured shortcuts and adds keyboard thumbnail actions.
• Fixes returning from Collections to Library and Enter on Cancel in destructive confirmation. Confirmation focus stays inside the dialog.
• Bumps only the desktop UI component to 1.5.0.

Validation: clean npm install, TypeScript, Vite production build, repository text policy and whitespace checks pass. The Playwright regression passes library filters/favorites, keyboard clip access, collection CRUD/cancellation, all eight settings pages, settings search/writes, shortcuts, recorder commands/errors/connection and 12 layouts across 1920/1280/960/800 px. A dedicated UI CI job runs this regression.

Windows/WebView2, actual media playback/capture, native dialogs and window controls still require a Windows smoke test. Existing audit O07 (pending/concurrent settings saves) and O12 remain open.
