Subject: [PATCH] =?UTF-8?q?fix:=20=E8=A1=A5=E5=85=A8=E5=BD=93=E5=89=8D?=
 =?UTF-8?q?=E5=8F=91=E5=B8=83=E6=84=8F=E5=9B=BE=E8=B7=AF=E7=94=B1?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

背景：普通的当前发布查询未进入联网能力包，且需要避免历史表达被误判为实时请求。

变更：新增带当前时间约束的新发布表达识别，按句切分并让明确历史年份优先；补齐否定联网、翻译、工具降级和核验优先级回归测试。

验证：3557 passed，Ruff、格式、架构与 diff 检查通过；对抗复审无 P0/P1。
