/// @brief      A task queue designed for managing compilation of pipeline state
///             objects for Vulkan backend.
///
///             This subclass uses a fml::BasicTaskRunner as the worker task
///             runner and dispatches compile jobs directly without sequential
///             processing constraints.
///
///             Key characteristics:
///             - Uses std::shared_ptr<fml::BasicTaskRunner> for
///             worker_task_runner_
///             - Dispatches jobs directly to the task runner in OnJobAdded()
///             - Does not implement sequential processing like GLES version
///
///             The Vulkan backend benefits from the parallel nature of pipeline
///             compilation, allowing multiple compile jobs to be processed
///             concurrently through the task runner.
