fix: switch crane pull to AWS ECR Public to avoid Docker Hub rate limits

manascb1344 · manascb1344 · commit 7f1b5a541ae9 · 2026-04-26T20:15:36.000+05:30
Docker Hub rate-limits unauthenticated pulls (100/IP/6hr). Modal's shared
build IPs exhaust this quickly. AWS ECR Public (public.ecr.aws/docker/library)
is the official Docker image mirror with NO anonymous rate limits.
