build-image.yml now pushes a moving :latest tag alongside :<short-sha>,
and a follow-up pin job (running in :latest) rewrites the image pin in all
three publish-*.yml to the new sha and commits it back to master with
FAPAT. Publish workflows keep immutable sha pins, kept current with no
manual bump. No rebuild loop: the pin commit only touches workflow_call
files. Root README image-flow section updated to match.
