Add App Store release pipeline, adopt ISC license, add unit test target

- Scripts/release.sh archives and uploads the macOS app via the
  appstore-publish skill's API-driven pipeline (xcodebuild + App Store
  Connect key, no fastlane); ExportOptions-macOS.plist adapts the skill's
  iOS-centric export options for generic/platform=macOS. Scripts/metadata/
  drafts the listing from the README. Canonical asc-*.swift scripts are
  referenced in place from indie-skills, matching Weight/HIIT.
- Replace the all-rights-reserved LICENSE.md with the portfolio-standard
  ISC license (REVIEW2 D2b), preserving the existing copyright year/holder.
- Add an IceGlassTests target (project.yml) with a real smoke test suite
  covering GameState's progression-rank ordering and polling-interval
  mapping — logic MainService relies on to reject stale API regressions.
