📝 Walkthrough

Walkthrough

Refactors cancellation token lifecycle management in the status auto-clear mechanism. The change reorders operations to capture the old CancellationTokenSource, clear the field reference, cancel and dispose the old token, then create and assign a new one. This eliminates overlapping cancellations and potential token reuse.
