Add MCPModel base class that inherits from Pydantic BaseModel with `extra="allow"` configuration for forward compatibility with protocol extensions. This change: - Creates MCPModel as a central base class for all MCP protocol types - Updates all protocol types to inherit from MCPModel (directly or indirectly) - Removes redundant model_config declarations from ~80 classes - Maintains the same runtime behavior while reducing code duplication The MCPModel pattern centralizes the `extra="allow"` configuration that enables MCP protocol types to accept additional fields not defined in the schema, which is essential for forward compatibility with future protocol versions.
