The release workflow runs on macos-14 when a v* tag is pushed (or on manual workflow_dispatch, which produces a draft release for dry runs). It builds the multi-platform XCFramework via Scripts/build-xcframework.sh with MLXSWIFT_USE_REMOTE=1, builds StableAudioCLI in release config with a colocated mlx.metallib, and publishes both archives plus a standalone PEP 723 version of prepare_weights.py. Release notes cover the Gatekeeper quarantine workaround for the unsigned binary and the uv-based weights prep flow. A separate CI workflow on pull_request / push to main verifies that swift build and a macOS xcframework slice still succeed.
The olilarkin/mlx-swift fork declares swift-tools-version 5.12, which Xcode 15.4 (Swift 5.10) cannot parse. Pick the newest installed Xcode instead, and download the Metal toolchain on demand since Xcode 16.3+ ships it as a separate component.

Summary
This PR adds GitHub Actions workflows for CI/release automation and introduces a standalone Python script for weight preparation that can be distributed independently to users.
Key Changes
.github/workflows/ci.yml): Automated builds on pull requests and pushes to main, including XCFramework compilation smoke tests and Swift package builds.github/workflows/release.yml): Automated release pipeline triggered on version tags or manual dispatch that:Scripts/prepare_weights_standalone.py): A self-contained, single-file Python script with PEP 723 inline dependencies that:Scripts/prepare_weights.pyuv runwithout cloning the repositoryImplementation Details
The standalone script uses PEP 723 inline script metadata to declare dependencies (mlx, numpy, huggingface_hub, typer), allowing it to be executed as a self-contained release asset without requiring users to clone the repository or manage dependencies manually.
The release workflow builds artifacts for both the XCFramework (for iOS/macOS development) and a CLI binary (for command-line usage), with the weights preparation script included as a third asset to complete the user experience.
