The412Banner 846b20f78a CI: re-pin the Debian image and stop the publish workflow replacing it (#501)
The publish workflow's push trigger fired again on the branch's rebase and overwrote the
release asset with a freshly compressed copy, so main's first build failed the checksum and
fell back to the registry pull. The env file now pins the asset as published; the workflow is
dispatch-only, defaults to a new tag, and refuses to replace an existing asset unless asked.

name: Publish the CI Debian image
# Pulls the Debian 11 image the x86 preloads build in, once, and publishes it as a release asset
# on this repo so build.yml never depends on a registry mirror's rate limit. Run it again (with a
# new tag) only to refresh the image; tools/linuxfs/debian-image.env names the one builds use.
