Contribution

• I am willing to submit a PR for this bug fix myself (please wait for maintainer approval in this issue first)

Start by running kimi web --host on version 0.39.0 and compare the web output with the CLI response, using the screenshots and the 0.38.0 behavior as references. Trace the web response-rendering entry point to identify where spaces become line breaks or duplicated lines. Done means the web view matches the CLI without duplicated lines or unintended new lines.
