enhance: auto-identify customers and add new tools

- Agent now auto-calls find_customer_by_identifier when user provides identifier
- Added register_customer and check_mcp_connection tools
- Refactored chat_hook to resume existing conversations from state
- Reduced default max_iterations (100) and timeout (15s)
