fix: flaky dbt Profiles Auto-Discovery tests in CI

`dispatcher.test.ts` nullifies the lazy registration hook via
`setRegistrationHook(null)` in its `beforeEach`. When Bun runs it
before `dbt-first-execution.test.ts`, the hook is permanently dead
and `Dispatcher.call("dbt.profiles")` throws "No native handler".

Fix: replace fragile lazy-hook reliance with explicit `beforeAll`
imports of the registration modules, guaranteeing handlers exist
regardless of test file ordering.
