Improve UI/UX for repository subscriptions and graph context

[jfrench9]

Summary

This PR brings UI/UX improvements to the repository management components and updates the graph context logic. Changes are synced from the core library (src/lib/core/) and include refinements to Active Subscriptions, Browse Repositories, and the graph context provider.

Key UI/UX Improvements

Active Subscriptions (ActiveSubscriptions.tsx)

• Enhanced component structure with improved layout and readability (~25 lines changed)
• Refined rendering logic for a better user experience when viewing active repository subscriptions
• Improved error handling or state management within the subscription display

Browse Repositories (BrowseRepositories.tsx)

• Minor adjustment to component behavior or rendering (single line addition)
• Likely an improvement to how repositories are displayed or filtered during browsing

Graph Context (graph-context.tsx)

• Updated context logic with refined state management (~8 lines adjusted)
• Improved how graph data is provided/consumed across the component tree, which may affect rendering performance and data flow reliability

Breaking Changes

None anticipated. The changes are incremental improvements to existing components and context providers. However, since the graph context is a shared provider, consumers of this context should be verified to ensure compatibility with any updated state shape or API.

Testing Notes for Reviewers

1. Active Subscriptions View: Navigate to the active subscriptions panel and verify:

   • Subscriptions render correctly with proper layout
   • Empty state, loading state, and error states display as expected
   • Subscription actions (add/remove) still function properly

2. Browse Repositories: Verify:

   • Repository listing renders correctly
   • Any filtering/search functionality remains intact
   • Navigation to/from the browse view works as expected

3. Graph Context: Verify:

   • Components consuming the graph context still receive expected data
   • No regressions in graph-related visualizations or data displays
   • Check for any console warnings related to context value changes

4. Cross-component Integration: Since both repository components and the graph context are modified, test workflows that span these areas (e.g., subscribing to a repository and seeing it reflected in graph views).

Browser Compatibility Considerations

• Changes appear to be logic and layout-level (React/JSX), so no browser-specific concerns are expected
• Standard testing across Chrome, Firefox, Safari, and Edge is recommended
• Verify responsive behavior if the Active Subscriptions layout changes affect mobile viewports
• No new browser APIs or CSS features appear to be introduced
