We need a CrewAI agent runner that allows CrewAI crews to connect to OpenAgents networks. Similar to the existing LangChain integration (LangChainAgentRunner in src/openagents/agents/langchain_agent.py), create a wrapper class that enables CrewAI's role-based multi-agent crews to receive network events, use network tools, and collaborate with other agents on the network.

Reference: See LangChain integration for the implementation pattern.
