Add the new model to the compatibility check.

When a gpt-5.1 request hits the premium limit, RunAIChat keeps chatOpts.Config.Model as gpt-5.1 and sets cont.Model to gpt-5.6-terra. AreModelsCompatible rejects that pair, so the backend returns cannot continue with a different model before sending the fallback request. (raw.githubusercontent.com)

The same check also rejects an existing gpt-5.1 or gpt-5-mini chat when a later request uses the new default. (raw.githubusercontent.com) Add the new model to the compatible set and cover both paths.

Review comment at @pkg/aiusechat/uctypes/uctypes.go at line 16:
Update AreModelsCompatible to include gpt-5.6-terra in the compatible model set, allowing both gpt-5.1 premium-limit fallback in RunAIChat and existing gpt-5.1 or gpt-5-mini chats to continue with the new default; add coverage for both compatibility paths.
