name: Release

# Tag-triggered: when `git push origin <version>` lands, this builds the
# release tarball + the live-installer ISO, and publishes them both to
# the Forgejo releases page. Boxes POST /api/furtka/update to pull the
# tarball; fresh-install users download the ISO from the release page.
#
# Runs on the self-hosted runner because iso/build.sh needs privileged
# docker access (mkarchiso wants root + loop mounts), and because the
# ubuntu-latest Forgejo hosted runner doesn't carry the docker socket
# bind-mount the build needs. Self-hosted adds ~5-7 min to the release
# (ISO build) but keeps the release page self-contained.
#
# Version tags only (CalVer like 26.0-alpha, 26.1, 27.0-beta). Random
# tags are ignored by the [0-9]* prefix.
