- Add send_voice() to upload audio and send as WeCom voice message - Add _upload_media() for WeCom temporary media store upload - Add _convert_to_amr() for ffmpeg-based audio conversion (WeCom requires AMR 8kHz mono) - Graceful fallback to text when voice upload/convert fails - Auto-cleanup of temporary converted files
- Handle incoming voice messages in _build_event (previously dropped) - Download voice audio from WeCom media store via _download_voice_media - Cache locally using cache_audio_from_bytes for STT transcription pipeline - Set MessageType.VOICE + media_urls so gateway auto-transcribes - Make _build_event async (requires media download) - Update tests to use async/await

WeCom voice messages are in AMR format which most STT engines don't support. Convert to WAV (16kHz mono) via ffmpeg before caching for transcription.

Overlaps with #8312 which also adds voice message support for the WeCom callback adapter. Maintainers should decide which approach to merge. |

Summary
Add voice message send support for WeCom (企业微信) callback adapter.
When the agent generates a TTS voice reply, the adapter now uploads the audio file to WeCom's temporary media store and sends it as a native voice message, instead of falling back to text.
