 * Builds the standard breadcrumb chain for a cluster-scoped Camunda webapp:
 *
 *   [Org ▾] > [Cluster ▾] > [App ▾]
 *
 * - **Org crumb**: shown when org data is available (SaaS). Label links back
 *   to web modeler for the current org. Dropdown switches orgs and lands on
 *   web modeler scoped to the selected org. Dropdown only renders when there
 *   is at least one sibling org and the current cluster exposes a modeler
 *   endpoint to derive sibling URLs from.
 * - **Cluster crumb**: shown when cluster data is available. Label links back
 *   to web modeler / console at the cluster level. Dropdown switches clusters
 *   while staying on `currentApp`, filtered to clusters that expose an
 *   endpoint for that app (alias-aware via `getEndpointForApp`).
 * - **App crumb**: always shown. Dropdown switches between sibling apps on
 *   the same cluster (filtered to apps with endpoints).
 *
 * Each dropdown follows the breadcrumb convention: clicking the label
 * navigates, clicking the chevron opens the dropdown. Items are listed in
 * source order with the current entry marked `isSelected`. Crumbs and
 * dropdowns are omitted when the underlying data is unavailable, so the same
 * hook works for both SaaS (full chain) and Self-Managed (partial or single
 * crumb) without any environment flag.
