+HTTP hooks can modify requests and responses. They apply to native models; AI
+SDK models do not currently pass through these hooks. Request and response
+bodies are one-shot streams. Use `clone()` when you intentionally need a
+separate reader, but be aware that its slower branch may buffer data. To inspect
+or modify chunks while preserving streaming, replace the body with one piped
+through a `TransformStream`.
