Reconciler behaviour:
- Creates an inventory of objects to be applied (persisted in-cluster under `.status.inventory`).
- Applies first custom resource definitions (CRDs) and namespaces, waits for them to register and only then applies the custom resources.
- Validates all resources with server-side dry-run apply (namespaced objects must contain `metadata.namespace`, defaulting to the `default` namespace is no longer supported).
- Reconciles only the resources that drifted.
- Prunes the objects that were previously applied but are missing from the current inventory.
- Emits events for only the resources that where created, configured or deleted.
