name: Release

# Manually triggered ("Run workflow"). On trigger it:
#   1. reads the version from package.json,
#   2. builds a self-contained bundle for every platform (one runner — there's no
#      native compilation, so cross-packaging is fine),
#   3. creates the GitHub Release (tag v<version>) with all archives, using the
#      release notes from CHANGELOG.md,
#   4. publishes the npm thin-installer (shim + per-platform packages).
#
# Before triggering: bump package.json and make sure CHANGELOG.md has the matching
# section (## [<version>], or ## [Unreleased]). Set the NPM_TOKEN repo secret.
