fix: align math server tools and agent prompt with available capabilities

- Updated system prompt in `mock_multi_agent.py` to reflect only supported tools
- Added error handling in `mock_math_server.py` to reject unsupported operations
- Ensured agent behavior stays within defined context and MCP protocol limits
