🧠 RAG Status 0 chunks

Clicking Index Content will: crawl NoteHeads.in + all your added resource URLs → split into 500-token chunks → embed each with Google's text-embedding-004 API → store vectors in Firestore knowledge_base collection. Prof. NoteHead will then use cosine similarity search instead of raw page dumps.

✅ No extra API key needed — uses keyword search, works with Firebase only.
