Python: Consider `create_agent` method renaming

[dmytrostruk]

Method create_agent is not related to remote agent creation. It exists to create ChatAgent instance, while remote agent creation is a responsibility of the service that supports it (e.g. AzureAIAgentClient). Based on that, name create_agent may be confusing for developers who expect their agents to be created remotely, when it's not always the case.

One of the potential alternatives is get_agent name.

Hm, that wouldn't be clearer to me

• get_agent sounds like you're fetching something that exists, to me, so it doesn't seem as clear? (the ChatAgent instance presumably does not exist yet)
• create_chat_agent would be a bit clearer to me, as it's creating a ChatAgent class, but I guess you don't like create. For comparison, langchain v1 uses create_agent, so I think "create" is a fine verb, it's just tricky here since agent-framework also supports hosted agents.
