# Local release — mirrors what the GitHub "Build & Release" workflow does on a tag push
#
# Usage:
#   ./scripts/release-local.sh          # read version from package.json
#   ./scripts/release-local.sh 4.21     # explicit version
#
# Steps:
#   1.  Bump version in package.json (if --version given)
#   2.  Create annotated git tag v<version>
#   3.  Build (npm run build:publish)
#   4.  Publish to npm (npm publish)
#   5.  Push tag to origin (so GitHub Actions finishes the release)
#
# Requires: npm login (NPM_TOKEN in ~/.npmrc), git push access
