- Replace Tabs with SegmentedControl in header, split into 1/3 sections
- Wrap all screens in Container for consistent margins
- Use Card instead of Paper for panel backgrounds across all screens
- Add SubscribeButton atom, CopyButton for resource URI
- Move annotations from ResourceListItem to ResourcePreviewPanel
- Improve AnnotationBadge colors for dark mode visibility
- Add Tools, Resources, and Prompts headers to list panels
- Add ConnectedLayout stories for Tools, Resources, and Prompts tabs
- Remove unused onCopy prop and copy button from PromptMessagesDisplay
