bump: patch type: fix Http.text and Http.header return copies. They handed back the handle's own buffer (and on macOS the response object's string), which Http.free then released: a text read before the free and used after it was garbage or empty - maroon-lake's map list wrote a 0-byte maps.json. Each call now returns a string that is the caller's to keep. Read a body once per response.
