Pull Request Overview

This PR introduces a base HTTPProtocol class to eliminate code duplication between the two HTTP protocol implementations (HttpToolsProtocol and H11Protocol). It extracts common initialization logic, attributes, and the connection_made method into the base class.

• Defines a new base HTTPProtocol class with shared initialization logic and common attributes
• Refactors existing protocol classes to inherit from HTTPProtocol instead of asyncio.Protocol
• Updates transport parameter types from asyncio.Transport to asyncio.BaseTransport for better type safety

The __slots__ declaration is missing the scheme attribute that is defined and used in the __init__ method and child classes. This could lead to runtime errors when trying to access the scheme attribute.
