chengyongru df6f9dd171 fix(wecom): use reply_stream for progress messages to avoid errcode=40008
The plain reply() uses cmd="reply" which does not support "text" msgtype
and causes WeCom API to return errcode=40008 (invalid message type).
Unify both progress and final text messages to use reply_stream()
(cmd="aibot_respond_msg"), differentiating via finish flag.

Fixes #2999
