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/

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.
- Web console Channels page: display active channels as config cards, support
save/connect/disconnect with real-time start/stop of channel processes
- Custom dropdown for channel selection (consistent with model selector style),
custom confirmation dialog for disconnect
- Fix channel stop: use sys.modules['__main__'] to access live ChannelManager
- Fix web request pending: move stop logic outside lock, set daemon_threads=True
- Fix reconnect: new asyncio event loop per startup, ctypes thread interrupt,
5s grace period before re-establishing remote connection
- Filter stale offline messages (>60s) pushed after reconnect
