Observe packet task failures to prevent unobserved overflow exceptions
Server dispatch and session enqueue operations create packet bus items without
waiting for delivery. When the pending-message queue overflows, Fail faults
the item's completion task, which can later raise UnobservedTaskException
even if the application handles the dropped-message notification.
Observe the completion task's exception inside MqttPacketBusItem.Fail. This
keeps the task faulted and preserves the original exception for existing and
future WaitAsync callers, including DeliverApplicationMessageAsync.
Add a garbage-collection regression test for failures without a waiter and
verify that requesting the task before or after failure preserves the original
overflow exception. Re-enable unobserved-exception tracking in the existing
overflow integration tests for both drop strategies.
Before the fix, the focused run failed the new unobserved-exception test and
both enqueue overflow tests. After the fix, all nine focused cases and all
489 tests in the .NET 10 Release test suite pass.
