Description

Zano HF6 support: upgrade zano_native_lib to a523871.

The HF6 release of zano_native_lib removed the raw _libs_ios OpenSSL and Boost archives the iOS build used to link against, and now ships prebuilt xcframeworks instead. This reworks the iOS path in update-sources.ts to compile the wrapper and link it against the prebuilt libzano-plain-wallet xcframework (which bundles Zano, Boost, and OpenSSL), while preserving the partial-link plus objcopy symbol localization so only zanoMethods and zanoMethodCount stay exported. Android is unchanged, since zano_native_lib still ships the raw _libs_android archives that path builds from.

The branch also carries a package-lock.json version sync (0.2.8 to 0.3.0) that the 0.3.0 release left stale.

Changes

• Update zano_native_lib to a523871 for HF6.
• Rework the iOS build to link against the prebuilt libzano-plain-wallet.xcframework.
• Add CHANGELOG entries for both.
• Sync package-lock.json to 0.3.0.

Testing

• Android: built all four ABIs (librnzano.so for arm64-v8a, armeabi-v7a, x86, x86_64) with no errors.
• iOS: built ZanoModule.xcframework (device slice plus fat simulator slice). Verified with nm that only _zanoMethods and _zanoMethodCount are exported and every other global symbol is localized.
• Integration: copied both artifacts into a local edge-react-gui node_modules/react-native-zano and built the iOS app (Release, simulator). Result was ** BUILD SUCCEEDED ** with the zano symbols present in the app binary and no link errors attributable to this module.

Note

Medium Risk
iOS native linking and dependency packaging changed in a security-sensitive crypto wallet module; Android is untouched but HF6 upgrades affect shipped binaries.

Overview
Bumps zano_native_lib to a523871 for Zano HF6 and documents the change in the changelog.

Reworks the iOS path in update-sources.ts: instead of CMake-building Zano and linking _libs_ios Boost/OpenSSL archives, the script compiles the wrapper with headers from the prebuilt libzano-plain-wallet.xcframework, partial-links against libzano-plain-wallet.a, and still runs objcopy so only _zanoMethods and _zanoMethodCount stay exported. Android sourcing and build flow are unchanged.

Also syncs package-lock.json to version 0.3.0 (was still 0.2.8).
