Task-executor scan scheduling could pass a null or invalid task handle into TimeSharingTaskExecutor. enqueue_splits and related paths cast the base TaskHandle to TimeSharingTaskHandle and immediately dereferenced the result, so a broken ScannerContext task-handle invariant caused BE to crash with SIGSEGV instead of returning a diagnostic error. This change validates scanner context, scan task, and task handle before submitting scan splits, and validates the task handle type at TimeSharingTaskExecutor entry points before dereferencing it.
