macOS: full support — MoltenVK auto-discovery, portability fix, and KytyPS5.app bundle (#394)

* macOS: auto-discover bundled MoltenVK on startup

On macOS the Vulkan loader comes from MoltenVK. SDL's default
probe only searches system paths, so a bundled libMoltenVK.dylib
next to the executable is invisible under the hardened runtime.

Probe it explicitly via SDL_GetBasePath() before falling back to
SDL's default search. Respect SDL_VULKAN_LIBRARY overrides and
log which loader is used. Update README to reflect that no
environment variable is required for bundled builds.

Co-Authored-By: internal-model

* window: fix Vulkan portability enumeration on macOS

MoltenVK requires VK_KHR_portability_enumeration and
VK_INSTANCE_CREATE_ENUMERATE_PORTABILITY_BIT_KHR to surface
portability devices via enumeratePhysicalDevices. Without the flag
the adapter is hidden on some driver versions, causing
"Could not find suitable device" failures.

Add the instance extension and flag when available, and add
diagnostic logs for all MoltenVK fallbacks (depthClipEnable,
colorWriteEnable, depthBounds, fragmentShaderBarycentric)
so black-screen diagnostics are actionable.

* macOS: add KytyPS5.app bundle packaging

Add a proper macOS application bundle when the launcher is built.
launcher becomes KytyPS5.app (CFBundleIdentifier org.kytyps5.kytyps5)
with KytyPS5 as the executable, and kyty_emulator is installed as a
helper inside Contents/MacOS so QCoreApplication::applicationDirPath()
finds it. MoltenVK is auto-discovered via SDL_GetBasePath() in that
directory, so no SDL_VULKAN_LIBRARY is required.

- src/launcher/Info.plist.in: minimal bundle plist (version from
  PROJECT_VERSION, LSMinimumSystemVersion 13.0).
- src/launcher/CMakeLists.txt: set MACOSX_BUNDLE, BUNDLE DESTINATION,
  install helper, re-sign helper with JIT entitlements, and invoke
  macdeployqt when available. Keep flat kyty_emulator for CLI.
- .github/workflows/build.yml: bundle MoltenVK into
  KytyPS5.app/Contents/MacOS when present, verify bundle artifacts
  (file/lipo/codesign), and handle bundle paths in the release zip.
- README.md: document bundle double-click and MoltenVK locations.

* launcher: fix bundle rpath for Qt frameworks

The bundle executable had @rpath references to Qt frameworks but no
LC_RPATH, causing dyld to abort at launch:

  Library not loaded: @rpath/QtConcurrent.framework
  Reason: no LC_RPATH's found

Set INSTALL_RPATH to @executable_path/../Frameworks and
BUILD_WITH_INSTALL_RPATH so the built and installed bundles
resolve Qt from Contents/Frameworks. Verified via otool -l
(LC_RPATH now present) and macdeployqt now succeeds without
"Cannot resolve rpath" errors.

* launcher: add Import game button

Add a prominent Import button to ConfigurationListWidget that lets
users select a game folder (containing eboot.bin) or a folder
containing multiple games via QFileDialog. Handles:

- Single game folder selected: adds its parent to game_dirs (Scan
  searches subdirectories, so parent is needed)
- Folder with multiple games: adds the selected folder
- Deduplication via PathKey/NormalizeGameDirectories, writes
  settings, rescans, and selects the imported game if found
- Shows info/warning dialogs when no games are found

UI: QToolButton with SP_DirOpenIcon and text Import beside the
existing toolbar, styled with a blue background for visibility.
Logic in ConfigurationListWidget::import_game().

* macOS: fix bundled loader and artifact packaging

* Revert "launcher: add Import game button"

This reverts commit 2f670ef95c.
