Inspect one image generator you own (its model and full config) at head or
a pinned version.
``generator_id`` accepts a UUID string. Platform ``system:...`` tier
aliases and system generator UUIDs are not returned here (NotFound):
system generators are run-only and their internal config never surfaces
through list, get, deploy, or revoke.
Defaults to the current version; pass ``version`` to pin. Returns the
full deploy-time payload (``provider``, ``model``,
``generation_contract``, ``default_params``) plus ``config_hash``
(SHA-256 over the config) so callers can detect drift across versions.
Requires ownership; a cross-user or revoked generator surfaces as
NotFound.
