Replace the Docker buildx + skopeo composite action with a Dagger Python module for building and publishing container images. BuildKit's native push is compatible with Zot, eliminating the skopeo workaround entirely. - Add Dagger Python module (.dagger/) with build/publish functions - Update build-container.yaml workflow to use `dagger call publish` - Add Dagger CLI to forgejo-runner image (v0.19.11) - Bump runner version to v2.6.0 in ExternalSecret - Add GPLv3 LICENSE - Add dagger to mise.toml Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# Generic container build workflow
|
|
# Triggers on tags matching: <container>-v<version>
|
|
# Builds from containers/<container>/Dockerfile if it exists
|
|
#
|
|
# Uses Dagger to build and push images to the Zot registry.
|
|
#
|
|
# Examples:
|
|
# nettest-v1.0.0 -> builds containers/nettest/
|
|
# devpi-v2.1.0 -> builds containers/devpi/
|
|
# foo-v1.0.0 -> skips if containers/foo/ doesn't exist
