Pull Request Overview

This PR refactors the MCP server architecture to externalize server instances, moving server creation responsibility from the library to the consumer. Instead of internally creating McpServer instances, the library now accepts either a pre-created server or a factory function to create servers.

• Removes internal McpServer instantiation and moves server creation to consumer code
• Adds validation for server/factory configuration with appropriate error handling and warnings
• Updates examples and documentation to reflect the new API requirements
