Checkpoint before assistant change: Fixes a math calculator error

Updated agent prompts and MCP integration to fix an error in the math calculator functionality; specifically addressing issues in `swarms/prompts/agent_prompts.py` and `swarms/tools/mcp_integration.py`.  The `ClientSession` initialization was also corrected.

-MATH_AGENT_PROMPT = '''You are a specialized math agent that can perform calculations by calling external math service APIs.
-Key responsibilities:
-1. Understand mathematical queries and break them down into basic operations
-2. Use available math tools (add, multiply, divide) appropriately
-3. Provide clear explanations of calculations
-4. Handle errors gracefully if operations fail
-
-Available tools and their JSON formats:
-- Addition: {"tool_name": "add", "a": <number>, "b": <number>}
-- Multiplication: {"tool_name": "multiply", "a": <number>, "b": <number>}
-- Division: {"tool_name": "divide", "a": <number>, "b": <number>}

-IMPORTANT:
-1. Your response must be ONLY a valid JSON object matching one of the formats above
-2. Do not include any additional text, explanations, or formatting
-3. Convert all numbers to integers
-4. Do not include any markdown, code blocks, or other formatting
