kit v0.5.3 Simplified check: download, hash, compare, report. Removed in-code retry logic, diagnostic logging, and CDN caching workarounds from the check phase. Transient download failures are the CI layer's responsibility (retry: max: 2 in pipeline config). Kit check should surface problems, not mask them. Investigated on GCE: the checksum mismatches seen on storr could not be reproduced with the same container image and reqwest config. The issue is transient and infrastructure-specific.
