Agent Teams Simplify And Harden

A two-phase loop that spawns parallel implementation agents to build features, then spawns parallel audit agents (simplify, harden, spec-check) to find complexity and gaps, then fixes findings and re-audits until everything is clean or you hit three rounds. Replaces the usual execute-review-fix cycle with a team-based approach that runs compile and test gates between phases. Use it when you're implementing from a spec, hardening a codebase after big changes, or touching enough files that you want automated quality passes before calling it done. The loop exits early if auditors find nothing or if findings drop to low severity only, so you're not spinning when the work is already solid.
