name: Release

# Builds the Docker image, the Windows installers (NSIS + portable) and the Linux
# AppImage, then publishes all of it: the image goes to the Gitea container
# registry as `latest` + the tag, the installers are attached to a Gitea release
# for that tag. Flatpak is intentionally not built here — flatpak-builder's
# sandbox (bwrap) needs working user namespaces, which a containerized Actions
# runner is not guaranteed to have; it stays a local-only step via
# scripts/publish.ps1.
#
# There is no Windows runner in this setup, so the "win" target (NSIS + portable)
# is cross-built on the Linux runner via Wine, the same path
# scripts/build-release.ps1 uses for -UseWsl. Unsigned either way.
#
# Requires two Actions secrets on this repo (Settings > Actions > Secrets), a
# token with package read/write *and* repository write (write:repository) scope:
#   GITEA_USER  - registry/API username
#   GITEA_TOKEN - registry/API token
