What & Why

Document how to build and install Formulus on x86_64 Android emulators.

The default Android build intentionally includes only ARM ABIs to keep APK size small. This update explains how developers using an x86_64 emulator can explicitly build the matching ABI with the existing abiFilters Gradle property, or use an ARM64 emulator image instead.

Closes #1034.
