/**
 * Process-local registry of cruise adapters.
 *
 * Templates register adapters at app startup:
 *
 *   import { registerCruiseAdapter } from "@voyant-travel/cruises/adapters"
 *   import { createCruiseAdapter } from "external-cruise-adapter"
 *
 *   registerCruiseAdapter(createCruiseAdapter({ token: env.CRUISE_ADAPTER_TOKEN }))
 *
 * The route layer resolves an adapter by `sourceProvider` (the prefix in the
 * unified key `<provider>:<ref>`) before dispatching detail reads, refresh,
 * detach, or the external booking commit.
 *
 * The registry is intentionally a plain Map. There's no per-tenant scoping —
 * each Voyant deployment is single-tenant. Tests can reset state via
 * `clearCruiseAdapters()`.
