feat: add starred repositories tab to user profile

[AbhiVarde]

What

Adds a Starred tab to user profile pages showing repositories the user has starred on GitHub.

Changes

• [owner]/page.tsx: fetches starred repos via getUserStarredRepos in parallel with existing data calls
• users/[username]/page.tsx: same fetch wired for consistency on the /users/:username route
• user-profile-content.tsx
  • Added StarredRepo interface
  • Added starred tab between Repositories and Activity
  • Responsive tab labels: shows Repos on mobile and Repositories on sm+
  • Starred repo rows display owner / repo format with avatar, description, language, star count, and fork count
  • Added empty state when the user has no starred repos

Notes

• Uses existing getUserStarredRepos, which calls octokit.activity.listReposStarredByUser
• No new dependencies or schema changes
• Fetching is handled inside Promise.allSettled, so failure never blocks the rest of the profile from loading
