New server enum values can make successful API responses fail during
parsing, including project lookups with a capability_based creator role.
Preserve known enum members and carry unfamiliar values as raw strings
or integers so reading and serializing newer responses stays compatible.

Generate explicit enum-or-primitive field types while retaining
constants and explicitly closed enums. Keep collaborator roles and
generic providers usable, and report unsupported evaluator types instead
of guessing their implementation. No API changes are required.
