BUG: Error thrown when calling HonoAdapter API with status code 204

[hongfanmeng]

When using HonoAdapter, the following error thrown when calling the API with status code 204

TypeError: Response constructor: Invalid response status code 204

This is because Hono only accepts an empty body when status code is 204, and the existing API returns an empty json {}.

To solve this problem, adding the following code to HonoAdapter in packages/hono/src/HonoAdapter.ts

+   if (response.status == 204) return c.body(null, 204);
    return c.json(response.body, response.status || 200);
