test: compare coding-agent response contracts across model tiers (#46597)
* test: compare coding-agent response contracts across model tiers

* test: reuse translation cases for coding-agent contracts

* test: name response compatibility group cross_model

* test: strengthen cross-model structure and stream preservation checks

* test: compare complete normalized streaming usage

* test: enable Haiku SDK stream checks after upstream fix
