CI: drop Android and iOS Hermes jobs from narrowed matrix

The previous narrowed matrix referenced js-engine inputs on build-android.yml and build-ios.yml, but the iteration-2 commit that added those inputs to build-macos.yml and build-ios.yml landed only on build-macos.yml and build-ios.yml on the local branch — the squashed PR commit didn't carry the build-android.yml / build-ios.yml diffs, causing GitHub Actions to reject the workflow with:

  Invalid input, js-engine is not defined in the referenced workflow.

Narrow further to only Win32 x64 + macOS Xcode 26.4 (the two job types that already accept js-engine on the PR head).
