Subject: [PATCH 1/2] ci: build & publish NemoTextProcessing.xcframework on
 release
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a workflow that runs build-xcframework.sh on a macOS runner (Xcode +
the four Apple Rust targets), producing NemoTextProcessing.xcframework
(macOS universal + iOS device + iOS simulator). Zips it, computes the
SwiftPM SHA-256 checksum, uploads both as a build artifact, and on a `v*`
tag attaches them (plus the Swift wrapper) to the GitHub release.

This lets Apple consumers (FluidAudio) link the native FFI via a SwiftPM
`.binaryTarget(url:checksum:)` instead of hand-linking libtext_processing_rs
— the prerequisite for enabling the native TN path by default.
