#   bootmenu/watchdog/mdns 复用未变；SDK meow_ui.a 不入固件；版本 0.7.54 → 0.7.62）
# 基线: fw_ssh（stock v1.4 + SSH 工具集），相对 M2.59 r3proii_m2_59.upt：
#   - usr/bin/meow_bootmenu   （M2.56，md5 536434c9：右下角版本读 /etc/meowos_version = 单点）

#   - etc/init.d/S89meow_svcd <- 开机自启 svcd（-f 前台 + 重挂循环，失败不死）；置于 S84ssh 后、S90 前。
#   - etc/meowos_version = 0.7.62
# 注意：SDK 的全局状态栏 / 全局左缘返回 / 通知 IPC（meow_notify_ipc）在 meow_ui.a（patch_v2/sdk/）侧，

# hello 等 SDK APP 走卡 MeowAPPs/ 热更新（build 惯例：不注入 usr/bin；搜索全部 m2xx 无 hello 拷贝）。
# 内容(相对 fw_ssh):
#   - usr/bin/meow_bootmenu       <- 静态 MIPS 开机引导选单（M2.56，md5 536434c9…；链入 meow_touch.c）
#   - usr/bin/meow_launcherd      <- MeowOS 主屏（最新，md5 a2b1c096…；静态链接 meow_touch.c + meow_settings.c + meow_ui.a/libz.a）
#   - usr/bin/meow_watchdog       <- 应用看门狗（M2.24，md5 ed711cc1，全面按键接管，未变）
#   - usr/bin/meow_svcd           <- 服务管理器（最新，md5 fb2d608b，status 配色美化）
#   - usr/bin/meow_mdns           <- 自研 mDNS 应答器（md5 b23de7ce…）
#   - etc/meowos_version          <- 版本号同源（0.7.62）
#   - etc/profile.d/meow_card_path.sh <- SSH 会话工具 PATH（M2.12 起）
#   - etc/init.d/S89meow_svcd / S90meow_bootmenu / S84ssh / S92_03_start_music_player / S95shutdown_logo
#   - etc/logo*.jpeg + etc/boot_animation/0.png + etc/shutdown_logo.jpeg（M2.1 补回）
# 字库（font.png+font.idx，1.22MiB）：放 TF 卡 MeowOS/fonts/（不动 rootfs）。固件不含字库。
# 明确: 无 S90meow_launcherd；S99ssh 已（改名 S84ssh）；stock hiby_player 校验 a73f2c49。
#      外围 CLI 已迁至卡 MeowOS/opt/bin/（本固件不含；卡不在时工具不可用，框架不受影响）。
