CLI E2E CLEANUP HITS THE BRAKES ON 429S

Shopify CLI just cut Accounts rate-limiting pressure by consolidating parallel cleanup jobs into a single sequential operation that reuses auth state.
The team shipped two interconnected fixes to their E2E test infrastructure. First, the auth state reuse pattern [1] stops redundant authentication during cleanup, which was hammering Accounts with concurrent login requests in CI. That gets paired with a structural fix [2] that moves app cleanup out of the sharded test matrix entirely, replacing it with a single follow-up job that runs after all shards complete. This eliminates the race condition where one shard starts deleting apps while another is still spinning them up. Both changes [1] and [2] landed in the main branch as of this morning. The engineering impact here is tangible: fewer 429s during CI runs, faster feedback loops, and a cleaner separation between test execution and teardown.
