MeowOS e6f0b665e3 refactor(launcher): 拆分 meow_launcherd.c(9778行)→meow_launcherd/ 多文件(agent-149) 
- 14 模块 .c + meow_launcher_internal.h(642): util/font_theme/fb_compositor/settings_page/power_menu/notif_center/app_launcher/main_menu/audio/backlight/net/keys/about/statusbar; meow_launcherd.c 已删
- 按行逐字搬移(0-diff), 118函数提升非static+47组extern(内部头), #if0退役区不编入(源码留.pre_split.bak)
- 关于本机小改: 作者 AskaEth/17 + info/item[13]防越界 + s_dd_modal 超高滚动(clamp/触摸滚动/音量键跟随/裁剪, 仅超高启用)
- build_launcher.sh 编译列表→模块; 文档/注释引用 meow_launcherd.c→模块/目录
- 编译0warning/-Wall -Wextra告警集与原文一致(77条无新增)/qemu-mipsel冒烟一致(--scan/--sysdump); launcher=c0799357(505KB; md5因多文件重编译与原文异,非回归依据)
- 备份 meow_launcherd.c.pre_split.bak/meow_launcherd.pre_split.bak; M2.69(0.7.64)已推卡并用户验证OK
