ci-cd-release-please.yml

# This workflow runs on every push to main and:
# 1. Checks if a new release should be created (via release-please)
# 2. If a release is created:
# 2.1. Checks for backend changes since previous release
# 2.2. If backend changes exist, builds and publishes Docker images with the new version
# 2.3. Triggers staging and yt01 deployment via repository dispatch
