-# Publish v1.x releases when a v1.* tag is pushed
-# This allows releasing from the v1.x branch without switching GitHub's default branch
-#
-# Automatic (latest v1.x):
-#   git checkout v1.x
-#   npm version patch  # bumps version and creates tag
-#   git push origin v1.x --tags
-#
-# Manual (for older minor versions like v1.23.x):
-#   1. Create a release branch: git checkout -b release/1.23 v1.23.1
-#   2. Apply your fixes
-#   3. Bump version: npm version patch  # creates v1.23.2 tag
-#   4. Push: git push origin release/1.23 --tags
-#   5. Run this workflow manually from GitHub Actions, specifying the tag
-#
-# The workflow will automatically build, test, and publish to npm.
