[opentelemetry-instrumentation-genai-agno] Add instrumentation for Agno Team, Workflow, and Model response methods.

[DylanRussell]

Description

Add instrumentation for the following methods:

Agno Class & Method(s)	SemConv Concept / Kind
Team.runTeam.arun	Agent (gen_ai.span.kind = AGENT)
Workflow.runWorkflow.arun	Workflow (gen_ai.span.kind = WORKFLOW)
Model.responseModel.aresponse	Inference (gen_ai.span.kind = LLM)

I'm not certain if it makes sense to model teams function call as a invoke agent span or if we might want to add a new sem conv span name for it.. But that is how both open inference and alibaba longsuite modeled it and it sort of makes sense. https://docs.agno.com/teams/overview#when-to-use-teams and https://docs.agno.com/workflows/overview#when-to-use-workflows describe the differences between workflows / agents / teams..

Next steps:

Add run_stream / arun_stream / response_stream / aresponse_stream using SyncStreamWrapper and AsyncStreamWrapper.
Add Parallel.execute and Parallel.aexecute wrapping for workflow parallel steps.
Enrich InputMessage / OutputMessage extraction to include tool calls, tool responses, and multimodal parts (for Model calls)
Instrument Step (awaiting on open-telemetry/semantic-conventions-genai#188)

Pull request overview

Adds additional Agno instrumentation coverage by patching Team, Workflow, Step, and Model response methods to emit GenAI spans via opentelemetry-util-genai, and updates package docs/tests accordingly.

Changes:

• Extend patching to Team.run/arun, Workflow.run/arun, Step.execute/aexecute, and Model.response/aresponse.
• Add unit tests covering Team + Model response instrumentation and basic Workflow/Step coverage.
• Document supported operations in README.rst and add a changelog fragment.

• This PR instruments Step.aexecute, but there is no corresponding async test coverage validating that span emission works for the async variant.

        wrap_function_wrapper(
            _AGNO_STEP_MODULE,
            f"{_STEP_CLASS}.aexecute",
            _step_aexecute(handler),
        )

• Skipping only on fastapi being absent may not cover other optional dependency/import failures in agno.workflow.step. It’s more robust to skip on importing the step module itself.

    pytest.importorskip("fastapi")
    from agno.workflow.step import Step  # noqa: PLC0415

LGTM, but the metric should be gen_ai.invoke_workflow.duration
