cindermark 0.2.0

name: Release (Apple XCFramework)

# MANUAL DISPATCH ONLY. This workflow runs on a macOS runner, which costs
# money (~$0.16/min). It is never triggered automatically — a maintainer
# dispatches it to cut a release:
#
#   1. Builds libcindermark.a for all 5 Apple targets.
#   2. Assembles CindermarkFFI.xcframework (device / sim-universal /
#      macos-universal slices + generated FFI header/modulemap).
#   3. Patches Package.swift with the release URL + computed checksum.
#   4. Commits, tags vX.Y.Z, and creates the GitHub release with the
#      zipped XCFramework attached — so the tag SwiftPM resolves always
#      has a valid binary target.
