Priority Job Queue

A lightweight client-side priority job queue module (v0.90.30) that uses a real-time ticker (every 100ms) to evaluate and run the highest-priority job. Jobs are modeled with status transitions (queued → running → complete/idle) and emit events on change. Supports serial and parallel job groups, dynamic priority changes, and scheduled/recurring jobs. Designed for browserify but also works server-side. No recent releases or significant changes since initial version.
