Python: [Bug]: AzureAIClient.as_agent() does not use agent_name for ChatAgent.name

[pjyi2147]

Description

AzureAIClient.as_agent() does not forward self.agent_name to the ChatAgent it creates. This causes ChatAgent.name to be None even when agent_name was provided to the AzureAIClient constructor, breaking observability/telemetry.

What happened?

• When creating an agent via AzureAIClient(agent_name="my_agent").as_agent(...), the resulting ChatAgent.name is None.
• The _trace_agent_run decorator in observability.py reads self.name for span attributes (agent_name=self.name), which evaluates to None.
• Telemetry spans show agent_name=None instead of the actual agent name.

What did you expect to happen?

• ChatAgent.name should default to self.agent_name when name is not explicitly passed to as_agent().
• Telemetry spans should correctly reflect the agent name.

Steps to reproduce:

1. Create an AzureAIClient with agent_name set.
2. Call .as_agent() without passing name=.
3. Observe that ChatAgent.name is None.

Code Sample

from agent_framework_azure_ai import AzureAIClient

client = AzureAIClient(
    credential=credential,
    agent_name="my_agent",           # agent_name is set here
    model_deployment_name="gpt-4",
)

agent = client.as_agent(
    instructions="You are helpful.",
)

print(agent.name)  # None — expected: "my_agent"


**Root cause in `agent_framework_azure_ai/_client.py`:**


# AzureAIClient.__init__ stores agent_name:
self.agent_name = agent_name  # e.g. "my_agent"

# But as_agent() does NOT use it as a default:
def as_agent(self, *, name: str | None = None, ...):
    return super().as_agent(name=name, ...)  # name stays None

Error Messages / Stack Traces

No error is raised — the issue is silent. `ChatAgent.name` is simply `None`, causing telemetry spans in `_trace_agent_run` (observability.py) to record `agent_name=<agent_uuid>`.

Additional Context

The AzureAIClient has two separate name concepts that are not bridged:

1. self.agent_name — used for server-side Azure AI agent creation (passed to project_client.agents.create_or_update)
2. ChatAgent.name (from BaseAgent) — used for OpenTelemetry observability via _trace_agent_run

as_agent() creates the ChatAgent but never connects these two. The _update_agent_name_and_description method only copies ChatAgent.name → AzureAIClient.agent_name (not the other direction), and since ChatAgent.name is None, the condition if agent_name is False, so nothing happens.

Current workaround: Explicitly pass name= to as_agent():

agent = client.as_agent(name="my_agent", instructions="...")
