# Binary Release workflow
#
# This workflow builds platform-specific binaries and creates a GitHub Release
# when a version tag (v*) is pushed. This is the second release channel —
# npm publishing is handled separately by version.yml via changesets.
#
# Release channels:
#   1. npm publish  — handled by version.yml (changesets/action)
#   2. GitHub Release with binaries — handled by this workflow (release.yml)
