write(
self,
file_path: str,
content: str,
) -> WriteResultWrite content using the LangSmith SDK to avoid ARG_MAX.
BaseSandbox.write() sends the full content in a shell command, which
can exceed ARG_MAX for large content. This override uses the SDK's
native write(), which sends content in the HTTP body, but preserves
the same existence check and parent-directory creation as
BaseSandbox.write().
