+规则标签页下，精简模式，和非精简模式一样要显示规则数量
+
+## Summary
+
+I have successfully modified `vite-frontend/src/pages/forward.tsx` to include the rule count ("{sortedForwards.length} 条规则") when the forward page is in the `compactMode` (精简模式) and `viewMode === "grouped"`. This ensures consistency with the regular view modes where the total rule count is already displayed.
+
+The fix was committed and pushed to the repository in the recent step:
+`fix(frontend): show rule count in compact view mode for forward pages`
