feat: add reusable ToolHealthBadge and ToolHealthBanner components

- Create ToolHealthBadge component in @tpmjs/ui for broken tool indicator
- Create ToolHealthBanner component in @tpmjs/ui for detailed health warnings
- Integrate both components into playground ToolsSidebar:
  - Badge shows in tool cards in left sidebar
  - Banner shows in tool detail modal
- Update search-registry to include health fields in API responses
- Add package.json exports for new health components

These components provide consistent UI for displaying broken tool status
across the application (tool search, tool detail pages, playground).
