ci: pin release to commit SHA and refine client stream logging

- Pin GitHub release creation to the exact commit SHA that triggered the workflow. This ensures releases are accurately linked to the build source, preventing potential discrepancies from rapid pushes.
- Elevate specific log messages related to JSON stream processing from debug to info level in the client library. Messages regarding incomplete buffers and successful JSON reassembly now provide better default visibility into streaming behavior, enhancing observability.
