Refactor the scheduler so all scheduleable work is wrapped in Arc<Work>, replacing the previous per-CPU wait_q design where sleeping tasks were bound to a specific CPU. Wakers now hold direct Arc<Work> references and can re-enqueue tasks on any CPU upon wakeup. Key changes: - Add Work struct wrapping OwnedTask with an AtomicTaskState and scheduler metadata (SchedulerData), replacing the old SchedulableTask. Remove Task::state (Arc<SpinLock<TaskState>>). Work::state is now the single source of truth for task state. - Rewrite the run queue using BinaryHeap-based eligible/ineligible split (EEVDF) with a dedicated VClock, replacing the BTreeMap linear scan. Extract vclock into its own module. - Rewrite wakers to hold Arc<Work> directly instead of looking up tasks by TaskDescriptor from TASK_LIST. - Replace lock-based sleep transitions in uspc_ret with atomic CAS (try_sleep_current) that correctly detects concurrent Woken state. - Simplify least-tasked-CPU metric to use only run-queue weight, since sleeping tasks are no longer bound to any CPU. - Add current_work() accessor.
