+      Fixed `operator-sdk run bundle` with `--security-context-config=restricted` to apply
+      the restricted security context to init containers (`registry-grpc-init`), not just
+      the main container. This resolves PodSecurity violations on clusters with
+      `restricted` policy enforcement.
