fix: Restore working Hugging Face deployment structure

Key changes to match the working pre-merge version:

1. Created symlink: analyzer -> src/analyzer
- HF was working when code was accessible at analyzer/ path
- Symlink allows import from "analyzer.chat.demo_app"

2. Updated app.py to import from analyzer not src.analyzer
- Matches the working version from commit 9b8e766
- Simple structure that HF Spaces expects

This restores the exact structure that was working before all
the merge/force-push issues started.
