Agent workflow

1. Identify the user's search intent from their message.
2. Extract a clean, specific query (avoid filler words).
3. Choose sonar for speed, sonar-pro for depth.
4. Run the command with python3 {baseDir}/scripts/perplexity_search.py --query "...".
5. Present the Answer and Citations to the user in a readable format.
6. Offer related questions as follow-up options.
