feat: M6.44+M6.45 收编 — 真机 0.8.45 现场保全(reader章节/key_router按键路由/WiFi连接修复/ncm bench+IME修复)

脏工作区现场收编：devdocs/local/m6_44_45_dirty_tracked.patch(46 个已跟踪文本文件,
+3090/-585, 已对 M6.43 基线干净适配) + m6_44_45_untracked_src.tar.gz 中 patch_v2/ 下
13 个新增源文件, 合成单个提交, 内容与容器工作树(R3ProII/patch_v2)逐字节一致。

- reader 章节: 新增 core/rdchapter.{h,c} — TXT 章节规范解析器, 扫描 512KB 码位对齐段文件
  逐段流式识别标题行(行首缩进≤4/显示宽≤40/行内标点≤1 三重约束防误判), 输出标题+全书字符
  偏移+段号/段内偏移+阿拉伯章号(中文数字归一), 首章前内容归"卷首"; book/reader/rdenc/
  rdlayout/settings 接入章节跳转与进度锚点, 附 chapter_smoke/turn_repro/build_turn_repro.sh
- key_router 按键路由: 新增 meow_launcherd/key_router.{h,c} — launcher-UI 页物理键统一路由
  (P1 仅音量键), 把读取边沿+防抖+长按 held+ramp 推进从 5 个会话收敛为进程内单开;
  各页每圈 key_router_pump() 取防抖后边沿, 动作(调音量/光标导航)仍由调用页决定,
  保留 run_menu 的 meow_mode 分支; App 前台 volume_page 武装时边沿抑制;
  main_menu/now_playing/notif_center/settings_page/subpage 接入, 附 test_key_router_vol/test_np_keys
- WiFi 连接修复: meow_netmgrd connect 有界等待 wpa_state=COMPLETED(普通 10s/隐藏网络 15s,
  env 可调)修设置页连接无响应; list_networks/scan_results 的 \xNN 转义还原始字节, 修中文 SSID
  永不命中致新建同名 open 记录顶影; launcher netmgr_ipc 配读超时; 附 test_wifi_connect(桩
  wpa_cli 驱动 static wifi_connect_ex), test_netmgrd.sh 补用例; wifi_page 同步
- ncm bench: 新增 bench/lyric_sim.c、bench/plpage_sim.c, vol_sync_sim 与 ncm core/app 同步
- SDK IME 修复: shift 大小写、K_ENTER 只提交不关、阻塞 IME 循环喂 on_tick 不被遮挡、
  IME 打开 ~200ms TAP 冷却窗吞 stray-TAP; 附 sdk/test_ime_fix.c
- 同期: meow_audiod 音量异步 ACK 线程(代际防 fd/槽复用竞态)、watchdog 音量收编(首选 audiod
  权威, settings.conf 覆盖路径)、panel 文件搜索(F1-④)与蓝牙只读详情(F1-③)、各类 build 脚本同步

范围红线: third_party/legado-E-main 原开发者未跟踪, 本次不入库(保留 devdocs/local tar 参考);
二进制不入库(后续重编); devdocs/ 不入库。59 文件全部在 patch_v2/ 下, 无 third_party/devdocs。
验证: git apply --check 干净; 59 文件 md5 与容器 patch_v2 逐一比对 59/59 一致(含
key_router.c/rdchapter.c/meow_ui_ime.c/test_wifi_connect.c 抽查); 可执行位保守
(check_lgpl_release.sh 100755, build_turn_repro.sh 100644 与容器一致)。
