GHSA-RMXW-PQ4X-3FVH goshs: File-based .goshs ACL authorization bypass via the ?bulk zip-download route (unauthenticated read; residual of GHSA-wvhv-qcqf-f3cx)

GHSA-wvhv-qcqf-f3cx fixed the per-folder .goshs ACL bypass on the state-changing routes PUT/POST upload/?mkdir/?delete and added recursive ACL resolution, and its description states the read/list path correctly enforces .goshs. That premise does not hold for the ?bulk zip-download route...
