Brummel c1971d4ed7 fix(cli): the graph render positional shape-discriminates op-scripts like its siblings
aura graph <op-script.json> exited 2 mislabeling the valid JSON array
as 'blueprint document is not valid JSON' — dispatch_graph parsed the
render positional with the envelope-only blueprint_from_json while the
introspect siblings (register, --params, --content-id) route through
composite_from_any. The render positional now uses the same
shape-discriminating path (made pub(crate)); an op-script renders
byte-identically to its built envelope, and a genuinely-bad document
gets the shared honest error including the unresolved-namespace hint
(preserved verbatim in composite_from_any's envelope arm).

Verified: RED test green, full workspace suite green (independent
mini-verify).
