launcher: add per-game config import and export

kernel: name guest threads on the host (#1106 )
PthreadCreate carries a guest thread name, but RunThread never handed it to the host, so every guest thread showed up as the same generic host thread name in core dumps, perf samples and htop. Call pthread_setname_np() on Linux so host-side diagnostics can attribute work to the guest thread that caused it.

+`_Build/linux/install` runs without a matching system Qt. FFmpeg is linked statically
+from the pinned [KytyPS5 FFmpeg core](https://github.com/KytyPS5/ext-ffmpeg-core)
+release, including VP9 and WebM support. System FFmpeg packages are not required.

+To build `kyty_emulator` and the `kyty_tests` target without Qt, use a separate build directory:
+
+```bash
+git submodule update --init --recursive
+
+cmake -S . -B _Build/linux-no-qt -G Ninja -DCMAKE_BUILD_TYPE=Release \
+  -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \

+```

 As on Windows, the MSVC compiler is not used; Clang is required. `cl.exe` is rejected at configure
 time.

 The CMake source root is the repository root.

+### Building on NixOS
+
+A development shell provides Clang, CMake, Ninja, Qt 6, the Vulkan headers, and the SDL3 backend
+libraries. Enter it and configure exactly as on other Linux distributions; the shell exports
+`CMAKE_PREFIX_PATH` and `QT_PLUGIN_PATH`, so the `-DCMAKE_PREFIX_PATH="$Qt6_DIR"` argument is not
+needed:
+
+```bash
+nix-shell # or: nix develop
+git submodule update --init --recursive
+
+cmake -S . -B _Build/linux -G Ninja -DCMAKE_BUILD_TYPE=Release \
+  -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
+
+cmake --build _Build/linux --target launcher --parallel
+cmake --install _Build/linux --prefix _Build/linux/install
+```
+
+The configure step downloads the FFmpeg prebuilts and the `xbyak`, `zydis`, `zstd`, and ZArchive
+sources, so it needs network access; a fully sandboxed `nix build` would require vendoring those
+inputs. A Vulkan 1.3 driver must be available at runtime (on NixOS,
+`hardware.graphics.enable = true`).
