docs(rum): drop the transient tracking-client caveat

The resource-collection issue it described is being fixed, so documenting it
would only churn the page. Removed from both the integration guide and the
compatibility limits, zh and en.

-**Known issue (`flashcat_tracking_http_client` 0.1.0)**: a request produces no resource event if its response body is consumed with `drain()` or `asFuture()`. Both replace the `onDone` / `onError` callbacks the SDK registers on the response stream, so resource collection starts but never finishes — silently, with no error reported. Use `toList()`, `transform()`, or a `listen()` with your own `onDone` instead.

 ## Identify users
 
 After sign-in, you can set the current user. The SDK writes the user fields to the `usr` object on subsequent RUM events.

 ## 关联用户信息
 
 登录后，你可以设置当前用户。SDK 会把用户字段写入后续 RUM 事件的 `usr` 对象。
