- P1：list_rebuild() 在 set_item_renderer/set_item_tier 后调用 meow_listview_set_container(g_lv,1)， 修正 SDK 默认 container=0（扁平满幅+分隔线）与任务要求的 MD3 圆角卡观感不一致 - P2：reader/lock/settings 桩头补接缝注释——on_create 在 meow_view_create 内运行且 activity 栈空， 非根页控件须 lazy 到 on_enter 或 push→建→pop；lock 另注明必须由自身 view on_event 消费 SWIPE， 否则左缘滑动绕过 PIN - 复验：宿主测试 46/46 PASS；交叉构建静态 MIPS32r2 ELF、-Wall -Wextra 零警告

/* ui/reader/reader.c — 阅读器页（ACT_READER，全屏）M3 骨架。
|
||
*
|
||
* M4 在此实现翻页/图片显示；本批只落可编译桩 + 既有接缝：
|
||
* - 书库经 mr_reader_open_dir(path) 导航进来（app.c/library.c 不改）；
|
||
* - 方向状态走 logic/reader 的 mr_reader_get/set_direction（默认 RTL）。
|
||
* 绘制走 view on_draw（注册表驱动），主题切换由 app.c 的 listener invalidate 全屏重画。
|
||
*
|
||
* 接缝注意（M4）：meow_view 的 on_create 在 meow_view_create 内运行（此时 activity 栈空），
|
||
* 本页是非根页——控件必须 lazy 到 on_enter 建，或照 hello demo_init 的模式
|
||
* meow_ui_activity_push(ACT_READER) → 建控件 → meow_ui_activity_pop()
|
||
* （examples/hello/ui/demo/demo.c:515-522）；否则控件 owner 绑到 ACT_LIBRARY，
|
||
* 造成跨页命中/绘制泄漏（§6.1）。
