Introduce a new channel that integrates with WeCom Customer Service
(微信客服), separate from the existing self-built WeCom app channel.
- Register channel type `wechatcom_kf` in factory, app loader and const
- Add config keys for token / secret / aes_key / port / cursor dir and
the first-start history-skip switch; also expose corresponding env vars
- Implement channel, message and cursor store under channel/wechatcom_kf/

When reloading a conversation, failed tool calls incorrectly showed checkmark instead of X because the is_error field was lost in the history rendering pipeline. Propagate is_error from DB extraction through to the frontend rendering to match the live SSE behavior.
Boot MCP servers (npx/uvx) on a background thread instead of blocking
agent init. Built-in tools serve traffic immediately while MCP comes
online; each new agent reads whatever is ready at creation time.
Idempotent via _mcp_loaded flag — concurrent sessions never re-fork
subprocesses. Per-server failures are isolated and warmup is triggered
in app.py so loading overlaps with channel startup.
- rewrite streaming reply to official cardkit v2.0 API (default on, auto-fallback)
- fix Whisper hallucination: bump ASR sample rate to 16k, pass language=zh
- fix lock-over-IO and tmp file cleanup from #2791
- drop deprecated feishu_bot_name; quiet unknown-key warnings
- docs: cardkit permission and feishu_stream_reply usage
- Receive audio messages: map msg_type=audio to ContextType.VOICE and
download opus file via lazy _prepare_fn for STT pipeline
- Send voice replies: upload opus audio via Feishu file API, auto-convert
non-opus formats (e.g. mp3) using pydub before upload
- Streaming text reply: inject on_event callback into context; send a
card
placeholder on first delta, then PATCH-update it in-place at a
configurable interval (feishu_stream_interval_ms) to achieve typewriter
effect; set feishu_streamed=True to suppress duplicate send()
- Enable NOT_SUPPORT_REPLYTYPE=[] to unblock voice and image reply types
- Fix AudioSegment mutation bug in audio_convert.py: set_frame_rate /
set_channels return new objects and must be reassigned
- Add -nostdin to ffmpeg invocation to prevent stdin deadlock in daemon
- Add feishu_bot_name, feishu_stream_reply, feishu_stream_interval_ms
config keys to config-template.json
