get_menu_widget 记录 EQUAL/CACHE_HIT/MISS 计数并对 menu-expand、 make_menu_widget 计时；replaceButtons 记录 SAME/REPLACE 计数与耗时； get_qactionlist 计时。TeXmacs/tests/1145.scm 在真实 GUI 中驱动 连续输入与进出数学模式，MOGAN_TEST_GUI=1 xmake r 1145 复现观测。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

push-focus 给菜单项注入 (invisible (tree->path t))，路径随光标位置 变化，毒化 get_menu_widget 的展开结果判等，menu_cache 永远 MISS， 每次进入数学模式都全量 make_menu_widget（~41ms）并重建 QAction。 新增 scheme 函数 menu-cache-normalize 归一化展开结果中的 invisible 载荷；get_menu_widget 改用归一化 key 做判等与缓存索引。invisible 载荷本就不参与 widget 构建，行为零变化。实测重复进入数学模式 update_menus 从 166-173ms 降至 121-156ms。 Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
