fix(mirror): verify with propagation patience — eager 404->delete deleted good uploads

Freshly uploaded GitHub release assets 404 on the download URL for a few
seconds; the verify loop treated that as a bad asset and DELETED it,
then re-uploaded and deleted again until the job timeout (0.0.86
publish-ecosystem). Verify up to ~18s before concluding failure; only
then delete + retry. Same patience on the GitCode side.
