subtree pull sdk 来自主仓 pub/sdk（主仓 commit 68ce46a 等）。新增： - 布局引擎 meow_ui_box / 动画基座 meow_ui_anim / 滚动物理 meow_ui_scroll - §6.4 事件分发形式化 / W_LISTVIEW 虚拟化多行 / meow_str 字符串资源 i18n - sb_icons 动作图标扩充 + topbar 位图图标 / meow_img_downscale - tools/ 图标生成脚本与 SVG 源 - 对应宿主 test_*.c 与 demo_box_scroll.c build_sdk.sh 冲突解析：保留公开仓自包含版（vendored meow_font + -Iinclude -I.）， OBJS 手工并入 4 个新模块（meow_ui_box/anim/scroll/str）。保留 vendored meow_font.c/ meow_ipc.h/meow_font.h/meow_notif.h，剔除宿主测试二进制与编译产物。

/* demo_box_scroll.c — 宿主离屏 demo：§12.1 meow_box 布局 + §12.3 meow_scroll fling 端到端。
|
||
* 渲染一屏「标题(固定) / 列表(weight 撑满) / 底栏(固定)」的 box 布局（cross 拉伸），
|
||
* 再对列表跑一次 fling（速度跟踪→惯性滑动到停止处），并 dump PPM 供目检。
|
||
*
|
||
* 编译（宿主 gcc，链真实 SDK 源 + 打桩 font/global）：
|
||
* gcc -o demo_box_scroll demo_box_scroll.c test_host_stub.c \
|
||
* meow_ui_gfx.c meow_ui_sys.c meow_ui_theme.c meow_ui_vol.c meow_ui_log.c \
|
||
* meow_ui_widget.c meow_ui_input.c meow_ui_activity.c meow_ui_dialog.c meow_ui_ime.c \
|
||
* meow_pinyin.c meow_ui_draw.c meow_ui_view.c meow_ui_box.c meow_ui_anim.c meow_ui_scroll.c \
|
||
* meow_ui_img.c meow_ui_media.c meow_notify_ipc.c stb_image.c \
|
||
* -I. -I../meow_launcherd -DMEOW_UI_HOST_TEST -pthread -lm
|
