Select update APK by device ABI and flavor

Update the in-app updater to detect device architecture (ABI) and build flavor (GMS vs FOSS) and choose the appropriate APK from GitHub release assets. echomusicupdater.kt now determines targetVariant and targetAbi, searches assets for a matching variant+ABI, falls back to a universal variant or the first APK if needed, and computes apkSizeInMB/browser_download_url accordingly.
