feat(loader): Qt6 GUI + strict wrap matcher + scaffold tweaks

Loader UI
  - Replace the Win32 ListView loader window with a Qt6 Widgets
    one. main.cpp + new MainWindow.h/cpp: QTableWidget showing
    PID / Window Title / Window Class, QTimer auto-refresh every
    1 s, double-click a row to inject. Title filter is built in
    (startsWith "Minecraft" and not containing "Launcher"), so
    HMCL / MultiMC / generic Java apps never show up.
  - Dark Fusion theme + inline QSS so the single EXE looks the
    same on any Windows version.
  - native/vcpkg.json declares qtbase[widgets] and build.gradle's
    new findVcpkg() detects VCPKG_ROOT / C:/vcpkg / D:/vcpkg /
    ~/vcpkg / D:/vcpkg-<version> and passes
    -DCMAKE_TOOLCHAIN_FILE + -DVCPKG_TARGET_TRIPLET=
    x64-windows-static so Qt is fully statically linked. Final
    OpenZenLoader.exe stays single-file (~30 MB) with no Qt6*.dll
    or vcruntime/msvcp DLL imports beyond Windows system DLLs.
  - Drop the old ui.cpp and the now-unused run_ui() entry on
    loader.h.

Patch transformer
  - asm.patchify.loader.PatchTransformer.wrapInvoke now tries a
    strict owner+name+desc match first, falling back to the
    historical (owner || name) matcher only if strict turns up
    nothing. The old loose matcher counted every Mth.*(FFF)F call
    against a wrap aimed at Mth.lerp(FFF)F, so a same-method
    sibling wrap that deleted its own site shifted later slice
    indices and made onRenderPitchLerp miss.

LivingEntityRendererPatch
  - With the strict matcher in place, onRenderPitchLerp's slice
    drops from (4,4) to (1,1) - there is exactly one
    Mth.lerp(FFF)F call site in LivingEntityRenderer.render
    (pitch lerp), as verified via javap on the runtime srg jar.
    onRenderHeadYawLerp keeps slice (2,2) (2nd of three
    Mth.rotLerp calls = head yaw). No more "no call site of
    m_14179_" warning at boot.

Scaffold
  - Rename the BooleanSetting field from advancedBlockSearch to
    sneak so the Java name matches the user-facing label ("Sneak").

README
  - Add the vcpkg / Qt prerequisites and update the injector
    usage section to describe the auto-refreshing UI + double-
    click flow.
