browserFetch calls res.json() directly, which throws SyntaxError when the API returns an empty body (content-length: 0). This happens when the Douyin hashtag search endpoint returns HTTP 200 with no content. Fix: read response as text first, return null for empty bodies, then throw a descriptive CommandExecutionError at the caller level. Fixes jackwener#1405
