feat(cli): graph register / --params accept the op-script form (fieldtest 0107 F5)

Both verbs now route through the same composite_from_any shape
discrimination file-mode --content-id shipped with (op-script array ->
one-build tail; envelope object -> loader), so the three on-ramp verbs
agree on accepted shapes and an op-script registers under the same
shape-invariant content id as its built envelope — no more raw serde
refusal ('invalid type: map, expected u32') hiding the graph build
bridge.

RED-first (tdd-author handoff): two same-seam behavioural pins
(register stores the envelope id for an op-script; --params matches
the envelope's axis lines) observed failing on the serde refusal, then
the two call sites rerouted.

Gates: workspace 990/0, clippy -D warnings clean.

closes #202
