AskaEth 3d70a3dd2c feat: M6.10–M6.19 批量收编 + M6.19 推卡验收
- M7 launcher 重写 5 期(虚拟化宫格/meow_theme 单一权威/横幅动画/自定义 PIN 键盘)
- OOM 通用化(cachegov 上收 SDK)、自动切歌根治、meowpanel jv_free 泄漏修复、Hello 滚动卡顿修复
- ncm 歌词 UI / 媒体通知封面 / 封面分辨率 640
- 5 bug 修复:ncm 后台化 UI 叠层+点击穿透、再进 ncm 桌面叠层、播放页新旧 UI 叠层抢刷脏区(meow_ui_gfx 恢复边沿整帧重画)、PIN 亮屏亮度跳(keys.c meow_panel_on 按 settings_brightness_clamped 恢复)、通知中心封面显歌单封面(cover.c save_cover_raw 加 is_song + 命中块守卫)
- 四 App 统一重链新 meow_ui.a 51caee4a;M6.19=0.8.19 固件 2d2331f2 推卡自刷验收全绿
