name: Release

# Manually triggered ("Run workflow"). Builds a self-contained bundle for each
# platform on its own runner (no cross-compile), publishes a GitHub Release with
# all archives, and publishes the npm thin-installer (shim + per-platform
# packages). Bump package.json + finalize the CHANGELOG before triggering.
