/**
 * Extend an app's live grant instead of replacing it.

 * The gateway keeps one grant per owner and app, and a new approval
 * replaces that grant's scopes. A request for `whoop.recovery` from an app
 * that holds `oura.sleep` would leave it with `whoop.recovery` alone, so a
 * request has to carry what the grant already covers.
 *
 * The merge itself lives in `@opendatalabs/vana-sdk` (`mergeWithLiveGrant`,
 * `unionGrantScopes`). This module only adds the CLI's flag-worded
 * requested/removed conflict check, run before any network call.
