…o host toolchain) Replicates .github/actions/build-linux in an Ubuntu 24.04 image. Extra packages vs CI docs (preinstalled on GitHub runners): make (mimalloc via media_kit_libs_linux), llvm (clang IPO probe), g++ (flutter_js hardcodes it). Also bundles libsqlite3 into the AppImage: package:sqlite3 dlopens 'libsqlite3.so', which does not exist on stock Ubuntu (only .so.0) — watch history is silently broken in the official AppImage/deb without it.
…loaded (AimesSoft#639 crash) VAAPI (and VDPAU) frames imported into an NVIDIA EGL context segfault in libnvidia-eglcore during player_texture_populate — the exact crash stack in issue AimesSoft#639 (hybrid AMD+NVIDIA laptop: VAAPI decodes on the iGPU, GL runs on the dGPU; reproduced with VDPAU on a desktop RTX 5060, driver 595.71.05). Keyed on /proc/driver/nvidia/version. Also migrates previously saved decoder orders, since selected_decoders persists the old default.
…ver, AimesSoft#639) next2_engine_render_gl_texture (librust_lib_nipaplay.so) segfaults inside libnvidia-eglcore on the raster thread during playback (gdb-verified on RTX 5060 / 595.71.05, Ubuntu 26.04 Wayland). Even when it does not crash, its per-frame GL rendering corrupts other textures in the shared context (green/blue frame corruption affecting every player kernel). Users can still select Next2 manually; only the default changes.
…creen, AimesSoft#639) The fork replaced upstream's isolated EGL context with 'reuse Flutter's current EGL context to avoid per-frame context switches'. That grabs whatever context is current on the platform thread at construction, while mpv_render_context_render later runs on the raster thread with Flutter's context current. mpv requires create/render on the same context; GL container objects (FBOs/VAOs) are never shared across contexts, so on NVIDIA the Libmpv kernel shows a blue screen / no video while audio and thumbnails work. Reverts linux/video_output.cc and linux/texture_gl.cc to the upstream implementation from third_party/media-kit-upstream (headers unchanged; verified 'H/W rendering with isolated EGL context', video displays).
…ang-bin/fvp#258, AimesSoft#307) player_texture_populate runs mdk::Player::renderVideo() inside Flutter's raster GL context with no state isolation from Skia/Impeller. Adds a GLStateGuard that snapshots the shared state, hands mdk clean defaults and restores everything afterwards. NOTE: unproven on the machine used for AimesSoft#639 diagnosis — the dark/bright symptom there turned out to be the Flutter 3.44 compositor (see PR). Kept because it is harmless and may matter on other setups (AimesSoft#307, wang-bin/fvp#258). mdk-sdk download artifacts are gitignored.
…icker) Flutter 3.44.x's GTK compositor (fl_compositor_opengl.cc) causes a dark/bright alternating flicker during video playback on Linux that stops whenever additional UI layers/windows repaint (single-layer glBlitFramebuffer fast path vs shader+blend composite; frames handed to GTK's paint context with only glFlush, no fence). The compositor rework that fixes it landed after the 3.44 branch cut and is not in stable 3.44.8; 3.47.0-0.3.pre is the first beta containing it. desktop_multi_window is adapted to 3.47's renamed internal windowing API (preferredSize/preferredConstraints -> size/constraints, 'decorated' removed) — this is why the branch no longer compiles on 3.44.x.

已合入最新 main，并将 Flutter 3.47 与 vendored 依赖隔离到 Linux；主线 3.44.6 和 HarmonyOS 3.35.8 保持独立。依赖解析、静态分析、完整测试及编译级验证均已通过。

合并摘要
解决 #639 中 Linux/NVIDIA 环境下叠加出现的播放崩溃、画面损坏、闪烁和 Libmpv 蓝屏问题，并保留原调查分支中针对 #307 的相关修复。
为可合并所做的整理
main（cb4cd8d2），解决原分支基于 v1.11.2 导致的冲突和功能落后。3.44.6。3.47.0-0.3.pre，通过.flutter-version-linux和pubspec_overrides.linux.yaml隔离依赖。3.35.8-ohos-1.0.1和pubspec_overrides.ohos.yaml。desktop_multi_window_linux_347兼容层；主线 3.44 和鸿蒙代码不受其内部 API 变化影响。验证
3.47.0-0.3.pre下 Linux 专属依赖解析成功。flutter analyze：0 issue。flutter build bundle --no-pub成功。actionlint。本次整理保留了原调查提交的一问题一提交结构，同时消除了原先“不适合合并”的全局 Flutter 升级、旧主分支基线和跨平台依赖污染问题。
Fixes #639.
