release workflow: Only publish 16KB APK (no -16k suffix), add native so max page size check

- Demo APK is now always built with 16KB page size, artifact named cgeDemo-{version}.apk
- Add validation step: all native .so in APK must have max LOAD align >= 16KB
- Release notes and docs updated to remove explicit 16k suffix, keep language natural
- AAR artifact structure remains unchanged
