feat(files): 新增外置系统文件管理器 os.meow.files (agent-183) — 目录浏览(虚拟化列表/空态)+文本预览(≤256KB截断)+删除/重命名/新建/属性(BottomSheet+IME)；路径写操作限 TF 卡内(拒 .. 越界)；多文件结构(app.c+ui/{browser,viewer}.c+ui/common/chrome.c+logic/fsx.c) 按批次②范本
files md5 6f6b0a6d; 0 warning; 宿主 test_fsx 全过(路径安全/格式化/排序/虚拟化/写操作/文本嗅探); qemu 离屏冒烟通过 SDK 缺口记录: listview 仅单行 label(本 App 用 custom 画布自绘行); common 档字库中文缺字(未声明 fonts:full) 真机待验证: 列表渲染/滚动手感/IME 重命名/弹窗交互

/* ui/browser.c — 目录浏览页（ACT_BROWSER，根页）view + 控制器。
|
||||
*
|
||||
* 职责：
|
||||
* - 持有目录态（g_cur 当前目录 / g_entries 缓存快照 / g_err 空态码 / g_scroll）；
|
||||
* - 内容区用 meow_widget_custom_create 自绘「虚拟化列表」：只画可见行（fsx_visible_range），
|
||||
* 行=图标(目录/文件)+名称+大小/时间+右侧 ⋯ 操作钮；不一次全读进内存（entries 有界缓存）；
|
||||
* - 空态/错误（无卡/空目录/权限）由 render_cb 内 app_draw_empty 画；
|
||||
* - 触摸：行 body=进目录/开预览；右侧操作钮或长按 → BottomSheet（删除/重命名/新建/属性）；
|
||||
* - 滑动：LEFT=返回上级（App 层处理）；UP/DOWN=列表滚动（本页）；
|
||||
* - 写操作只经 logic（fsx_*），且在卡内校验后执行。
|
||||
*
|
||||
* 颜色全部读 meow_theme_get() 语义色（§8.1），不硬编码。
