## Title

    [OpenAI Agents SDK voice] STTWebsocketConnectionError 'Timeout waiting for transcription_session.created event' (on Python 3.10 surfaced as bare asyncio.TimeoutError)

## Body

    Cause (Maintainer-confirmed cause): Setup waits for created/updated events with a timeout; on 3.10 asyncio.TimeoutError is distinct from builtin TimeoutError so the wrapping except clause did not match (maintainer-linked fix PR #5075).
    
    Fix status: fixed_upstream
    
    Limitations:
    - Issue details read via WebFetch summarizer; release version containing PR #5075 not verified.
    
    Other error fragments:
    - Timeout waiting for transcription_session.updated event
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/openai/openai-agents-python/61e98ab7bd0d993eed4c65bb8b68320075227417/src/agents/voice/models/openai_stt.py (official_docs, unknown, documented_behavior): _setup_connection wraps setup timeouts as STTWebsocketConnectionError with these messages; _wait_for_event now re-raises asyncio.TimeoutError as builtin TimeoutError with a comment about Python 3.10.
    - https://github.com/openai/openai-agents-python/issues/5074 (github_issue, 2026-09-17, maintainer_confirmed_cause): Report: on Python 3.10 the setup timeout escapes as asyncio.TimeoutError with empty message instead of STTWebsocketConnectionError; closed with linked PR #5075; present in v0.22.2.
