This pull request refactors the scope management system within the PTO2 runtime, replacing dynamic task tracking with a range-based approach using task IDs per ring. It unifies task and heap allocation into a single PTO2TaskAllocator and updates the shared memory layout and documentation accordingly. Additionally, branch prediction hints were added to hot paths. Feedback suggests that the removal of a prefetch in pto2_prefetch_payload might negatively impact performance for tasks with a high number of inline fanins.
