name: Devcontainer image

# Builds the dev container base image used by .devcontainer/devcontainer.json
# (VS Code Dev Containers + GitHub Codespaces) and publishes it to GHCR.
#
# Triggers only on push to main (path-filtered) and manual dispatch. PRs
# don't trigger this workflow — devcontainer.json references the :latest
# tag, so pre-publishing per-PR images would just produce unused tags.
# A broken Dockerfile change in a PR will surface when the merge to main
# fires this workflow; the previously-good :latest stays in place until
# the next successful run.
