Rationale for this change
The Go binding was not releasing heap-allocated strings returned by the C API after converting them into Go strings.
This could lead to memory leaks in repeated metadata queries such as
Info()and during large list operations. In addition, the C binding did not provide a dedicated API for releasing owned strings, which made the ownership contract harder to follow for managed-language bindings built on top of the C API.What changes are included in this PR?
This PR introduces a dedicated C API to release owned strings returned by the C binding and updates the Go binding to use it when handling string results.
It also updates the related C binding documentation and tests to reflect the new ownership contract, and adds Go regression tests to cover the affected paths.
Are there any user-facing changes?
No breaking user-facing API changes.
The main visible change is that the C binding now provides a dedicated string release API for bindings that consume owned strings from the C layer.
