* and `gcTime`. By default, the detection treats a missing `window` (or the presence of a
* `Deno` global) as server.
*
* Override this for runtimes where that default detection would give the wrong answer — for
* example, a Service Worker, where `window` is undefined even though the environment should
* behave like a client.
* @example
* ```ts
* import { environmentManager } from '@tanstack/query-core'
*
* environmentManager.setIsServer(() => false)
* ```
