[BUG] Public profile /u/[username] shows blank page for users with zero public repositories

[vbarik317-droid]

Bug Description

Describe the bug
When a user has no public repositories on GitHub, visiting their DevTrack public profile at /u/[username] renders a blank or broken page instead of a graceful empty state.

Steps to reproduce

1. Create or use a GitHub account with 0 public repos
2. Sign into DevTrack
3. Visit /u/[your-username]

Expected behavior
A friendly empty state message like "No repositories to display yet." should appear.

Actual behavior
Page renders blank or throws a runtime error.

Suggested fix
Add null/empty-array guards in the public profile data fetch and render a fallback UI component.

Environment

• Next.js App Router
• src/lib/public-profile-data.ts

Steps to Reproduce

1. Go to '...'
2. Click on '...'
3. See error

Hi @vbarik317-droid,

I would like to work on this issue under GSSoC'26.

My approach:

• Reproduce the issue using a GitHub account with zero public repositories.
• Investigate the data flow in src/lib/public-profile-data.ts and the corresponding public profile page components.
• Add proper null/empty-array checks to prevent runtime errors when repository data is unavailable.
• Implement a user-friendly empty state UI with a message such as "No repositories to display yet."
• Test the fix to ensure profiles with and without repositories render correctly without regressions.

I can submit a PR soon after assignment.

Thank you!
