fix: add Android ELF build IDs

[jvsena42]

Summary

Add -Wl,--build-id=sha1 to the Android linker configuration for every published LDK ABI. Google Play uses ELF build IDs to match packaged native libraries with uploaded debug symbols.

Deliverables

• Preserve the existing linker and 16 KB page-size flags.
• Bump the cross-platform package version.
• Refresh the tracked mobile release artifacts.
• Publish the versioned Android artifact and its existing native debug-symbol archive.

Acceptance criteria

• The Android linker configuration includes -Wl,--build-id=sha1 for armeabi-v7a, arm64-v8a, and x86_64.
• The repository's ordinary build, test, and lint checks pass.
• The versioned Android artifact is published.
• Bitkit Android adopts the released artifact.

Coordination

• Epic: epic: add Android ELF build IDs bitkit-android#1105
• Implementation: fix: add android elf build ids #98
