WalkthroughThe change adds system-managed install namespace support behind the BoxcutterRuntime feature gate. User-provided namespaces are validated before bundle application. Storage migration skips extensions without a namespace. ChangesInstall namespace management

Merge Risk: 🔵 Low · up to 9c327 The current behavior works, but its no-op test would not catch an unintended Helm lookup added later. Tightening the mock improves regression protection. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

When spec.namespace is empty the applier stops passing WithSelfManagedInstallNamespace, so the renderer resolves the install namespace from bundle metadata and emits the Namespace object itself. This is gated on BoxcutterRuntime; with the gate off an empty spec.namespace is a terminal configuration error rather than a silent fallback. Signed-off-by: Nader Ziada <nziada@redhat.com>

Use a strict action-client mock in this no-op test.
newMockActionGetter allows ActionClientFor, Get, and History with AnyTimes(). A future Migrate change could perform a Helm lookup before returning without failing this test. Use an action getter with no allowed calls, or let the helper disable its default expectations for this test.

Description
When spec.namespace is empty the applier stops passing WithSelfManagedInstallNamespace, so the renderer resolves the install namespace from bundle metadata and emits the Namespace object itself. This is gated on BoxcutterRuntime; with the gate off an empty spec.namespace is a terminal configuration error rather than a silent fallback.
_second of three PRs splitting #2825. This one is applier.
validateSystemManagedNamespaceUnchanged from the original branch is deliberately omitted while the requirement is being discussed. It blocked an upgrade whose bundle resolves to a different namespace, by listing namespaces with the extension's owner labels and comparing._
summary
applier/provider.go
New IsNamespaceManagementEnabled field. If spec.namespace is empty and the gate is off, Get() returns a terminal config error. If spec.namespace is set, it passes WithSelfManagedInstallNamespace as before; if empty, it omits the option so the renderer resolves the namespace and emits the Namespace object.
applier/boxcutter.go
Migrate() returns early when spec.namespace is empty — a managed-namespace extension never had a Helm release, so there's nothing to migrate.
controllers/clusterextension_reconcile_steps.go
New ValidateInstallNamespace step. Checks a user-provided spec.namespace exists and fails retryably if not, so the user can create it and the next reconcile succeeds. No-ops when the namespace is system-managed.
cmd/operator-controller/main.go
Sets IsNamespaceManagementEnabled from the BoxcutterRuntime gate, and inserts ValidateInstallNamespace(coreClient) into the boxcutter step list between UnpackBundle and ApplyBundleWithBoxcutter.
Tests
Gate coverage in provider_test.go, the migration skip in boxcutter_test.go, and TestValidateInstallNamespace plus a direct test of the system-managed short-circuit in clusterextension_controller_test.go.
Only the namespace existence check is live today. Everything else waits on the CRD change in PR 3.
