fix(cloudflare): pass through structured array/object values as-is

A block-referenced array/object value was being blindly stringified
before the JSON-shape check, so String([...]) comma-joined arrays and
String({...}) produced the literal "[object Object]" instead of the
JSON shape Cloudflare expects (e.g. for ciphers). Already-structured
values now pass straight through.
