    /* D11.10.151-补 152 fix31: assistant 消息撑满父级, 避免长文本被 max-width:75% 截断
       根因: 父级 .chat-message.assistant 是 max-width:100% (覆盖 90%), 但 .message-content 是 max-width:75% + fit-content,
             当内容超 75% 父级时, fit-content 让容器变宽到内容宽, 但 max-width 又卡住,
             配合 overflow-x:hidden → 文字被裁切, 用户看到"超出边界被截断"
       修法: assistant 的 message-content 改 max-width:100% (撑满父级), 由父级 90% 限制最大宽度
             配合 .chat-md-host 的 overflow-wrap:break-word / word-break:break-word, 长内容自然换行
       风险: 改 100% 后 assistant 消息可占满 90% 父级 — 这是预期效果 (原本就该这样, 不应被 75% 卡住)
