Reproduce the JSON display issue in the Electron app on Windows using the reported 0.5.1 environment, then trace where the returned JSON is rendered or serialized. Done means Chinese text such as “新增” appears directly instead of Unicode escape sequences such as "\\u65B0\\u589E".

Written by the indexing model from the issue text.
