Move WAV loading to asyncio.to_thread so realtime audio sends do not block the event loop. Add coverage for the offloaded read and preserved payload metadata. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com> Copilot-Session: 1c85c49c-2d6c-4050-b3e3-ce085c97c5ec

Description
RealtimeTarget.send_audio_asyncperformed synchronouswave.open()andreadframes()calls on the event loop, which could stall concurrent realtime audio requests.This moves WAV loading into a synchronous helper executed with
asyncio.to_thread. The audio bytes and WAV metadata continue through the existing API payload and output-saving path unchanged.Tests and Documentation
