# Release workflow — runs on any tag that starts with 'v' (e.g. v2.0.0-rc1).
#
# Responsibilities:
#   1. Run the full test suite with the race detector.
#   2. Build and publish binaries for macOS / Linux / Windows (amd64 + arm64)
#      via goreleaser-action.
#   3. Attach them to a GitHub Release whose body comes from .goreleaser.yml
#      headers + CHANGELOG entries.
#
# What you need:
#   - Nothing beyond the default GITHUB_TOKEN that Actions provides. goreleaser
#     uses it to create the release.
#
# To cut a new release locally:
#   git tag -a v2.0.0-rc1 -m "v2.0.0 RC1"
#   git push origin v2.0.0-rc1
# Then watch the run under "Actions → Release".
