tesselation support in GUI

Preserve native Windows paths for filesystem operations, command-line options,
and game icons. Complete Unicode handling in recursive file listings and file
logging, restore unmounting by host directory, and extend regression coverage.

Original implementation by Augusto Domingos (@AghastyGD); retain all five of
his PR commits and include the reviewed follow-up fixes.

Closes #714

+// API version changelog:
+//
+// 1.0.0 - initial release
+// 1.0.1 - Bugfix: IsFrameCapturing() was returning false for captures that were triggered
+//         by keypress or TriggerCapture, instead of Start/EndFrameCapture.
+// 1.0.2 - Refactor: Renamed eRENDERDOC_Option_DebugDeviceMode to eRENDERDOC_Option_APIValidation
+// 1.1.0 - Add feature: TriggerMultiFrameCapture(). Backwards compatible with 1.0.x since the new
+//         function pointer is added to the end of the struct, the original layout is identical
+// 1.1.1 - Refactor: Renamed remote access to target control (to better disambiguate from remote
+//         replay/remote server concept in replay UI)
+// 1.1.2 - Refactor: Renamed "log file" in function names to just capture, to clarify that these
+//         are captures and not debug logging files. This is the first API version in the v1.0
+//         branch.
+// 1.2.0 - Added feature: SetCaptureFileComments() to add comments to a capture file that will be
+//         displayed in the UI program on load.
+// 1.3.0 - Added feature: New capture option eRENDERDOC_Option_AllowUnsupportedVendorExtensions
+//         which allows users to opt-in to allowing unsupported vendor extensions to function.
+//         Should be used at the user's own risk.
+//         Refactor: Renamed eRENDERDOC_Option_VerifyMapWrites to
+//         eRENDERDOC_Option_VerifyBufferAccess, which now also controls initialisation to
+//         0xdddddddd of uninitialised buffer contents.
+// 1.4.0 - Added feature: DiscardFrameCapture() to discard a frame capture in progress and stop
+//         capturing without saving anything to disk.
+// 1.4.1 - Refactor: Renamed Shutdown to RemoveHooks to better clarify what is happening
+// 1.4.2 - Refactor: Renamed 'draws' to 'actions' in callstack capture option.
+// 1.5.0 - Added feature: ShowReplayUI() to request that the replay UI show itself if connected
+// 1.6.0 - Added feature: SetCaptureTitle() which can be used to set a title for a
+//         capture made with StartFrameCapture() or EndFrameCapture()
+// 1.7.0 - Added feature: SetObjectAnnotation() / SetCommandAnnotation() for adding rich
+//         annotations to objects and command streams

 Testing games and submitting detailed bug reports are useful ways to contribute. Search existing
 issues first, then use the **Game Emulation Bug Report** template and attach the complete log file.

+Code contributions should be focused, build successfully on the platforms they touch, and include
+relevant tests where practical. Windows is the primary target, so a change that alters shared code
+should not regress it; changes confined to a platform's own code paths only need to build there. Because KytyPS5 is still evolving quickly, consider opening an issue before
 starting a large change.

+### Building on Linux
+
+Install the toolchain and the libraries the bundled SDL2 needs. Without the audio, Wayland and
+udev development packages SDL2 quietly configures itself without those backends, and the resulting
+build has no working sound and no gamepad hotplug:
+
+```bash
+sudo apt-get install --no-install-recommends \
+  clang lld ninja-build cmake git glslang-tools pkg-config \
+  libgl1-mesa-dev libx11-dev libxcursor-dev libxext-dev libxfixes-dev \
+  libxi-dev libxrandr-dev libxss-dev libxkbcommon-dev \
+  libasound2-dev libpulse-dev libudev-dev libdbus-1-dev libwayland-dev wayland-protocols
+```
+
+Qt 6 (Concurrent, Network, Widgets) is also required — either the distribution packages
+(`qt6-base-dev`) or an official Qt installation.
+
+```bash
+git submodule update --init --recursive
+
+cmake -S . -B _Build/linux -G Ninja -DCMAKE_BUILD_TYPE=Release \
+  -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \
+  -DCMAKE_PREFIX_PATH="$Qt6_DIR"
+
+cmake --build _Build/linux --target launcher --parallel
+cmake --install _Build/linux --prefix _Build/linux/install
+```
+
+The install step copies the Qt libraries and plugins next to the binaries, so
+`_Build/linux/install` runs without a matching system Qt. FFmpeg is linked statically
+from the pinned [KytyPS5 FFmpeg core](https://github.com/KytyPS5/ext-ffmpeg-core)
+release, including VP9 and WebM support. System FFmpeg packages are not required.
+
+As on Windows, the MSVC compiler is not used; Clang is required. `cl.exe` is rejected at configure
+time.
+
+The CMake source root is the repository root.
+
+### Building on NixOS
+
+A development shell provides Clang, CMake, Ninja, Qt 6, the Vulkan headers, and the SDL2 backend
+libraries. Enter it and configure exactly as on other Linux distributions; the shell exports
+`CMAKE_PREFIX_PATH` and `QT_PLUGIN_PATH`, so the `-DCMAKE_PREFIX_PATH="$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` 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`).
+
+### Building on macOS
+
+macOS builds target x86-64 and run under Rosetta 2 on Apple Silicon, so the PS5's x86-64 game
+code executes through the same translation layer as the emulator itself. Prebuilt archives are
+attached to releases; the steps below are for building from source.
+
+Requirements:
+
+- An Apple Silicon Mac with Rosetta 2 installed (`softwareupdate --install-rosetta`)
+- Xcode (or the Command Line Tools)
+- Homebrew packages: `brew install cmake ninja glslang`
+- Qt 6 (Concurrent, Network, Widgets) with x86-64 support. The official Qt installation is
+  universal and works; Homebrew's Qt is arm64-only and will not link
+
+```bash
+git submodule update --init --recursive
+
+cmake -S . -B _Build/macos -G Ninja -DCMAKE_BUILD_TYPE=Release \
+  -DCMAKE_OSX_ARCHITECTURES=x86_64 \
+  -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \
+  -DCMAKE_PREFIX_PATH="$Qt6_DIR"
+
+cmake --build _Build/macos --target launcher --parallel
+cmake --install _Build/macos --prefix _Build/macos/install
+```
+
+The build re-signs `kyty_emulator` with the JIT entitlements it needs to execute translated
+guest code; no manual signing step is required. When the launcher is built, the install
+also produces `_Build/macos/install/KytyPS5.app` — double-click to launch the GUI.
+A flat `kyty_emulator` is kept for CLI usage.
+
+Vulkan comes from MoltenVK. Download `MoltenVK-macos.tar` from the
+[MoltenVK releases](https://github.com/KhronosGroup/MoltenVK/releases), then copy
+`MoltenVK/dynamic/dylib/macOS/libMoltenVK.dylib` next to the flat `kyty_emulator`
+(and, for the bundle, into `KytyPS5.app/Contents/Frameworks/`) and ad-hoc sign it:
+
+```bash
+codesign --force --sign - _Build/macos/install/libMoltenVK.dylib
+# For the bundle (if present):
+codesign --force --sign - _Build/macos/install/KytyPS5.app/Contents/Frameworks/libMoltenVK.dylib
+codesign --force --sign - _Build/macos/install/KytyPS5.app
+```
+
+Release archives already include a signed `libMoltenVK.dylib` (both flat and inside the bundle).
+
+### Regression tests
+
+Build every regression executable and run the registered tests with:
+
+```powershell
+cmake --build _Build/windows --target kyty_tests
+ctest --test-dir _Build/windows --output-on-failure
+```
+
+Use `_Build/linux` instead of `_Build/windows` for a Linux build.
+
 ### Visual Studio Code
