[enhancement] Add .env.example to frontend directory

[pragnyanramtha]

Enhancement Description

The backend directory has a .env.example file, but the frontend directory doesn't. Users need to know to create frontend/.env.local with Supabase keys.

Location

frontend/ directory

Current State

• ✅ backend/.env.example exists
• ❌ frontend/.env.example does NOT exist

Suggested .env.example Content

NEXT_PUBLIC_SUPABASE_URL=your-supabase-project-url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your-supabase-anon-key
NEXT_PUBLIC_API_URL=http://127.0.0.1:8000

Why This Matters

New contributors won't know what environment variables to set for the frontend without reading the README carefully.

Labels

Hi @pragnyanramtha

I can add the frontend .env.example file!

What I'll do:

1. Create frontend/.env.example file
2. Add required environment variables with placeholders
3. Add helpful comments explaining each variable
4. Match the style of backend/.env.example

Also, could you please add the NSoC'26 label to this issue for tracking?

Please assign this to me.

Thanks!
