真机 M6.3 反馈（bcef8e0 三连修复未好全，追加两问题）：
P1 锁屏 PIN 输入穿透仍在（媒体保活 App 实时读 evdev）
根因：媒体保活 App（播放中）从不 SIGSTOP（保 PCM），SDK 输入线程实时读 evdev，不走缓冲。
bcef8e0 的「SIGCONT 排空」只作用于冻结 App；对未冻结 App，隔离全靠 /tmp/meow_notif_active
让 SDK 排空——若 App 的 meow_ui.a 缺该排空（或节流窗内漏网），锁屏期触摸依旧抵达 App。
修法：run_lock_screen() 与 lck_input_pin_modal() 打开 DEV_TOUCH 后 EVIOCGRAB 独占触控设备
（真机 goodix 实测 EVIOCGRAB 返回 0）——抓取期事件只投递抓取者、不为其它 fd 缓冲/回放，
故**任何**前台进程（冻结或未冻结）锁屏期都收不到触摸（真全模态）。失败时记日志降级
（仍靠标记+SIGSTOP 隔离）。overlay_gate.h 增 overlay_keepalive_needs_grab 判据。
P2 主界面应用名只显示 5 字（「流媒体客户」式，半字残形）
根因：app_launcher.c `strncpy(a->name, name, 16)` 仍把显示名硬截 16 字节——M6.3 只扩了
name[49]+json_str 整序列，漏改此二处。UTF-8 下 16B = 5 汉字 + 「端」首字节 + 无 NUL，
显示成「流媒体客户」+ 残形；main_menu.c menu_name_fit 按字节回退又停在半截字符、加 "..." 溢出。
修法：新增 meow_utf8.h（meow_utf8_char_len / meow_utf8_copy_bounded，纯决策可单测）——
app_launcher.c 两处 strncpy(16) 改 app_name_copy(=copy_bounded, 拷满 sizeof name=49)；
menu_name_fit 改整字符前进 + 预留省略号宽度（mfont 用「…」/点阵用 "..."），总宽 ≤ maxw，
绝不劈开多字节字符。
新增 test_utf8_name.c（14 断言：整字符长/整序列有界拷贝，含 cap=16/17/12 边界不劈字）+
test_overlay_gate.c 扩展（S1b 未冻结 App 靠 EVIOCGRAB 隔离 4 断言）。launcher 全量宿主回归
+ SDK 叠加/状态栏/输入回归全 PASS；mipsel 交叉 -Wall -Wextra 0 warning。
md5 56dac860841c3884b4322707246e22af（/usr/bin 只读，待固件打包 M6.4；fw_content.conf 未动）。

* - 正确 → 进主屏（return 1）；锁屏页期间电源键=息屏（允许再睡，return 0），音量键不动；
|

* 不响应左缘返回 / 通知中心手势（本函数不实现这些手势，触摸只认键盘 tap）。
