fix: update stock analyst agent logic to handle financial queries properly

- Refined `mock_multi_agent.py` to parse and route stock-specific inputs correctly
- Addressed issue where StockAnalyst returned fallback prompts instead of actionable responses
- Improved overall agent logic for financial data interpretation and reply generation
