Async Pr Review

This one spins up background PR reviews that won't block your terminal. It checks out the PR in a temporary git worktree, runs your preflight checks, generates test plans, and does a full code review using headless LLM calls, all while you keep working. Later you ask for status and it synthesizes everything into a single recommendation. The worktree isolation is clever since it sidesteps git lock issues entirely. Best for larger PRs where you want deep analysis but don't want to babysit the process. The tradeoff is you're firing off autonomous agents that rack up token usage in the background, so know what you're signing up for.
