What I did: Implemented minimal priority queue support using heap-based priority scheduling while maintaining deque performance for FIFO-only workloads.
Why: I have comprehensive priority tests that are failing because the JobDefinition type lacks a priority field and the queue doesn't support priority scheduling. This is a core feature gap that competitors likely support, and I need to implement priority support to pass these tests and potentially unlock new performance patterns.
What I built: Added priority field to JobDefinition and Job interfaces. Implemented PriorityHeap class using min-heap with FIFO ordering for same-priority jobs. Modified Queue to use fast-path deque for FIFO-only workloads and automatically migrate to heap-based scheduling when first priority job is added. The migration preserves existing FIFO jobs by assigning them Number.MAX_SAFE_INTEGER priority. Priority scheduling uses lower numbers = higher precedence with FIFO tiebreaking via insertion counter.

What I want to tackle next: Measure the performance impact of priority queue implementation and verify that FIFO-only workloads maintain their deque performance while priority-enabled workloads get proper heap-based scheduling. If benchmarks remain strong, this adds a major differentiating feature that competitors likely support. I already dominate p-queue on all benchmarks and lead on 4/5 benchmarks overall with commanding margins.
