Pull Request Overview

This PR refactors status updates to be asynchronous by introducing a dedicated status handler and replacing direct Status().Update calls with non‐blocking enqueues.

• Added a new status package with UpdateHandler, Updater interface, and UpdateWriter for async status updates.
• Updated manager setup to register the UpdateHandler and pass its writer to controllers.
• Refactored controllers to gather status.Update entries in TranslateContext and enqueue them via Updater.Update.

internal/manager/controllers.go:101

• The IngressClassReconciler is instantiated without the Updater field, which prevents async status updates for IngressClass. Add Updater: updater, to this struct literal.

• [nitpick] No unit tests were added for the new UpdateHandler; consider adding tests for its Start, apply, and Writer behaviors.

[nitpick] The repeated status.Update closures across controllers introduce duplication; consider extracting a helper function to build these updates.
