Validation and JSON boundary helpers for the A2A 1.0 data model.

A2A 1.0 uses ProtoJSON oneof members. In particular, Parts contain one of text, raw, url, or data; stream responses contain one of task, message, statusUpdate, or artifactUpdate. The pre-1.0 kind discriminator is deliberately rejected at this boundary.
