xamal

Cut a Xamal release end-to-end (maintainer-only). Does the version-bump prep, then commits, pushes master, tags vx.y.z (last), and watches the Release workflow publish to Hex and create the GitHub Release. Use when the user wants to "release x.y.z", "publish to Hex", "tag and ship", or "cut a release". Requires push rights; the tag push triggers CI which needs HEX_API_KEY. For local prep only (no push), use the version-bump skill.

Prepare a new Xamal version locally — bump @version in mix.exs, roll the CHANGELOG.md
