## Number-Based Reference System

The bot uses a number-based reference system for ease of use:
1. User runs `!fragen` to get a list of questions
2. Bot stores the list internally for the user
3. User can reference questions by their list number
4. Numbers are valid until the user runs a new list command

This allows simple commands like:
- `!frage 3` - Show details for question #3
- `!recherche 1 deep` - Start deep research for question #1
- `!antwort 2` - Show answer for question #2
