- Replace Message struct with type alias for inference.Message (backward compat)
- Remove convertMessages() — types are now identical via alias
- Extend GenOpts with TopK, TopP, RepeatPenalty (mapped in convertOpts)
- Deprecate StreamingBackend with doc comment (only 2 callers, both in cli/)
- Simplify HTTPTextModel.Chat() — pass messages directly
- Update CLAUDE.md with Backend Architecture section
- Add 2 new tests, remove 1 obsolete test

InferenceAdapter wraps inference.TextModel (iter.Seq[Token]) to satisfy
ml.Backend (string returns) and ml.StreamingBackend (TokenCallback).
- adapter.go: InferenceAdapter with Generate/Chat/Stream/Close
- adapter_test.go: 13 test cases with mock TextModel (all pass)
