Wire up 음악퀴즈_test manifest to local test artifacts

Fill empty platform.downloadUrl / modsFolder / resourcepackPath / serverPath
so the test pack drives a complete installer flow end-to-end.

Test artifacts (gitignored, must be present locally under file/):
  file/platforms/fabric-installer.jar  (real fabric installer 1.0.1)
  file/mods/music-quiz/music-quiz-test-mod.jar  (stub fabric mod)
  file/resourcepacks/music-quiz.zip  (stub resourcepack)
  file/maps/music-quiz-map.zip  (stub world)
  file/servers/music-quiz-server.zip  (stub server with eula.txt=false to exercise EULA popup)

mcVersion "26.1.2" left as user authored; not a real MC version,
so 게임 실행 단계는 실패할 수 있음 — installer flow itself runs through.
