Function: detectHost()
function detectHost(): HostIdentity;
Defined in: host.ts:26
Detect where the SDK is running. A DOM document plus location.origin
means a browser (PWA, <rasd-form>, iframe — inside an iframe the frame's
own origin, which is what location.origin already is); everything else is
Node/SSR/CI. React Native is never detected: @rasd/license has no
platform APIs, so the host passes appId to createLicense explicitly
(docs/15 §4.2) and the handle constructs the native identity itself.
