…braries (#20106) ## Summary Adds iOS cross-compilation support for the barretenberg-rs FFI backend: - Add `ios.toolchain.cmake` from leetal/ios-cmake project for iOS cross-compilation - Add iOS CMake presets (`ios-arm64` for device, `ios-sim-arm64` for simulator) - Add `build_ios` function to bootstrap.sh for macOS runners - Add iOS static library packaging to `build_release_dir` - Update `build.rs` to support iOS targets (`aarch64-apple-ios`, `aarch64-apple-ios-sim`) - Update README with iOS supported targets - Update `publish-bb-mac.yml` workflow to build and release iOS static libraries on tag push ## Supported iOS Targets - `aarch64-apple-ios` - iOS device (arm64) - `aarch64-apple-ios-sim` - iOS Simulator on Apple Silicon Macs ## How it works iOS builds cannot be cross-compiled from Linux (requires Xcode/iOS SDK). The `publish-bb-mac.yml` workflow: 1. Triggers on `v*` tag push (including `ci-release-pr` test tags) 2. Runs on `macos-14` runner with Xcode 3. Builds `bb-external` target for both iOS presets 4. Packages and uploads `barretenberg-static-arm64-ios.tar.gz` and `barretenberg-static-arm64-ios-sim.tar.gz` to GitHub release The main Linux release (ci3.yml) handles Linux and macOS (via zig cross-compile). iOS is handled separately by this workflow. ## Notes iOS builds are configured to: - Target iOS 14.0+ - Disable ARC (Automatic Reference Counting) - Use the Ninja generator ## Test plan - [X] Add `ci-release-pr` label to trigger test release - [X] Verify `publish-bb-mac.yml` workflow runs on macOS runner - [X] Verify iOS presets configure and build successfully - [X] Verify `barretenberg-static-arm64-ios.tar.gz` and `barretenberg-static-arm64-ios-sim.tar.gz` are uploaded to the test release
