Refactor Scenario to Decouple Adapters

[aviralgarg05]

Description

The Scenario class in src/agentunit/core/scenario.py has hardcoded from_* methods for every adapter (OpenAI, CrewAI, AutoGen, etc.).
This violates the Open/Closed Principle. Adding a new adapter currently requires modifying the core Scenario class.

Proposed Solution

Implement an Adapter Registry or Plugin system.

• Scenario should genericize instantiation or lookup adapters from a registry.
• New adapters can register themselves without touching core code.

Task

• Design a registry mechanism.
• Refactor Scenario to use the registry.
• Migrate existing from_* methods to use the registry or deprecate them in favor of a generic factory.
