描述

We've had lots of problems with std::snprintf. E.g. #418.

As BillyGoto says:

Could we switch to std::ostringstream instead? Its numeric formatting is actually specified in terms of printf's output, and it's everywhere.

研究方向
First, identify all uses of std::snprintf in the codebase, likely in files under src/lib json/. Replace each with std::ostringstream for numeric formatting. Ensure the output matches the expected JSON format and that existing tests pass. Refer to issue #418 for context on problems with snprintf. No open PRs or assignees, making this a clean task for a first time contributor.
