# Gitea Actions: Docker Build, Push, and Notify
#
# CI/CD pipeline for Major Domo Discord Bot:
# - Builds Docker images on every push/PR
# - Auto-generates CalVer version (YYYY.MM.BUILD) on main branch merges
# - Supports multi-channel releases: stable (main), rc (next-release), dev (PRs)
# - Pushes to Docker Hub and creates git tag on main
# - Sends Discord notifications on success/failure
