v2.4.0

Features

• baoyu-wechat-summary: add an @bot Q&A section to both the normal and roast digests. Messages mentioning @bot / @精华bot (customizable via the new bot_aliases preference) are detected during the skeleton pass and answered in a dedicated section — earnest and helpful in the normal version, snarky-but-substantive in the roast version. Answers draw only on the chat context and the model's own knowledge (no web access) and honestly flag anything that needs real-time data
