# Builds the Galaxy stack and (re)deploys it into the long-lived dev
# environment on the host running this Gitea Actions runner. Triggered
# on every merge into `development`. Branch protections on `development`
# guarantee the commit already passed `go-unit`, `ui-test`, and
# `integration` as part of the PR that produced this push, so this
# workflow does not re-run those tests — it focuses on packaging and
# rollout.
#
# `workflow_dispatch` is also accepted so a developer can deploy any
# branch (typically a feature branch under active review) into the
# shared dev environment from the Gitea Actions UI without waiting for
# the PR to merge first. The deploy job picks up whatever the chosen
# ref is — same packaging + healthcheck steps as the merge path.
