## Summary by CodeRabbit
* **New Features**
* Added the `FLEET_MDM_CERTIFICATE_PROFILES_LIMIT` configuration option
to control the number of certificate authority (CA) profiles installed
during each Apple MDM profile reconciliation cycle. This new setting
enables administrators to throttle CA profile installations and manage
installation performance during normal reconciliation operations across
large-scale deployments. Set this value to 0 to disable throttling.
