Ultrawork

A parallel execution engine that fires off multiple independent tasks simultaneously instead of running them one after another. It handles context gathering, builds dependency graphs for complex work, and routes tasks to the right model tier (Haiku for simple fixes, Sonnet for standard work, Opus for gnarly refactors). The key thing to understand is that it's just the parallelism layer. It doesn't do persistence or verification loops on its own. If you need that, ralph wraps ultrawork and adds those pieces. If you just want to kick off three independent PRs at once and manage completion yourself, this is the component you want.
