Move the Dagger module from .dagger/ to the repo root (src/blumeops/),
rename from blumeops-ci to blumeops, and introduce native Dagger pipelines
that replace docker_build() for container builds.
docker_build() swallowed build errors — native pipelines surface full
output per step. Navidrome is the first container migrated as a proof of
concept (containers/navidrome/container.py).
- Containers with container.py use native Dagger builds
- Containers with only Dockerfile fall back to docker_build()
- dagger call container-version extracts VERSION from container.py
- CI workflow, container-list, container-version-check, and
container-build-and-release all updated for hybrid mode
