### What problem does this PR solve? Issue Number: resolve Problem Summary: When a Baidu RPC client receives a `SerializedResponse`, its payload is appended from a temporary `IOBuf` using the copy-style overload. This does not copy payload bytes, but duplicates `IOBuf` BlockRefs and performs corresponding reference-count operations before the temporary buffer is destroyed. ### What is changed and the side effects? Changed: Use `IOBuf::movable()` when appending the received payload to `SerializedResponse`. The BlockRefs are transferred directly because the source buffer is not used afterwards. Side effects: - Performance effects: Reduces BlockRef traversal and reference-count increment/decrement operations on the serialized-response receive path. Benefits are expected mainly for high-QPS or fragmented/large responses. - Breaking backward compatibility: --- ### Check List: - Please make sure your changes are compilable. - When providing us with a new feature, it is best to add related tests. - Please follow [Contributor Covenant Code of Conduct](https://github.com/apache/brpc/blob/master/CODE_OF_CONDUCT.md). -- This is an automated message from the Apache Git Service.
