# Container images, built only when a release is published (08 §3.1). Runs on GitHub Actions and
# Gitea Actions (both read .github/workflows); each pushes to its own registry:
#   GitHub: ghcr.io/<owner>/selfphoneng-{api,asterisk,probe} (the job's GITHUB_TOKEN)
#   Gitea:  <gitea host>/<owner>/selfphoneng-{api,asterisk,probe} (secrets REGISTRY_USER + REGISTRY_TOKEN:
#           a personal access token with write:package; Gitea's job token can't push packages)
# Tags: the version (0.0.1), plus <major>.<minor> and latest; a pre-release gets the version and dev.
# The release also gets the probe as downloads (selfphoneng-probe-linux-{x64,arm64}, .cjs, SHA256SUMS).
