Rewrites priv/baselines.exs and emits the content-addressed snapshot.
Recomputes only files and tree_digest; generator_version and every other
human-owned field is preserved. Run this after regenerating a baseline tree,
then attach the archives to the release:
mix capstone.baseline.record
gh release upload v<version> *_<version>_*.tar.gzEach archive is named <type>_<version>_<last 8 of sha>.tar.gz — the manifest
key, this project's version, and enough digest to distinguish. The version in
the name is the one the release tag carries, so the glob above selects exactly
the archives this run produced and leaves an earlier release's behind.
