# Triggered by pushing a tag (v*)
# pub.dev OIDC requires tag context, so we trigger on tag push
#
# Release process:
# 1. Update version in pubspec.yaml, podspec, CHANGELOG.md
# 2. Commit and push to main
# 3. Create and push tag: git tag v0.2.5 && git push origin v0.2.5
# 4. Workflow runs automatically and publishes everywhere
