Special notes for your reviewer:

Implementation notes:
Initialization: Every place that sets status.ready = true/false now also sets status.initialization.provisioned (or status.initialization.controlPlaneInitialized for control plane types).

Conditions: Each scope's PatchObject() method now mirrors the existing v1beta1 Ready summary condition into status.v1beta2.conditions as a metav1.Condition of type Ready (plus Available for AzureManagedControlPlane, per the ControlPlane contract). The patch helper declares these as owned v1beta2 conditions via WithOwnedV1Beta2Conditions.

TODOs:

• squashed commits
• includes documentation
• adds unit tests
• cherry-pick candidate

Release note:

Dual-write v1beta2 initialization and conditions in controllers
