Description

This publishes vss-client-android 0.5.17 with Android native libraries that keep full DWARF .debug_info metadata and 16 KB LOAD alignment for Bitkit Android release symbolication.

This PR:

• Aligns the Android package and Swift package release to 0.5.17.
• Regenerates Android JNI libs with cargo ndk --no-strip.
• Uses Android NDK r28c and Android linker flags for 16 KB LOAD segment alignment.
• Exports ANDROID_NDK_ROOT via $GITHUB_ENV after setup-ndk.
• Fails shell and Gradle publish validation if libvss_rust_client_ffi.so lacks .debug_info or 16 KB LOAD alignment.
• Preserves libvss_rust_client_ffi.so symbols through Gradle release AAR packaging.
• Updates direct publish docs and Gradle publish workflow to regenerate Android bindings before Gradle build/publish.
