A Manifest published without its amd64 DIST entry bricks emerge for
every amd64 user, which is worse than failing the job; a 3x30s retry
absorbs release-asset propagation lag right after the tag. Also
documents the #557 root cause at the top: the overlay must never be
edited by hand — an ebuild change without Manifest regeneration is a
guaranteed digest mismatch; template changes are republished by
re-dispatching this workflow.
