Add Ctrl+K/Cmd+K command palette search

Replace the TopBar dropdown search with a cmdk-based command palette opened via a visible trigger button (with platform-aware shortcut badge) or the Ctrl+K/Cmd+K global shortcut. Shared search logic moves to a useGlobalSearch hook; the palette reuses the existing ui/command components.
