Story

Based on the OSImageStream parsing logic built in https://issues.redhat.com/browse/MCO-1956 inject that logic in the reconcile loop and the bootstrap logic to ensure each time the cluster is deployed or updated the OSImageStream CR is updated to reflect the available resources.

Take the POC as a reference: https://issues.redhat.com/browse/MCO-1957

Acceptance Criteria

• The OSImageStream resource is always updated to the latest available streams
• The MCP and ControllerConfig resources are not touched and still use the cluster-wide images (the default stream)

Technical Notes:

• No Kubernetes controller code yet - just the stream building logic
• Should be usable from both bootstrap and runtime contexts
