Axiom Build Performance

Summary

This is a routing skill that figures out which specialized build tool you need when iOS compilation breaks. It covers the usual suspects: environment issues before code debugging, slow builds, SPM conflicts, and Xcode misbehavior. The routing logic is sensible, it sends you to xcode-debugging for mysterious failures, build-performance for slow compilation, and various agents for specific problems like TestFlight crashes or hang diagnostics. The "environment first" philosophy is right, most BUILD FAILED mysteries are zombie processes or stale Derived Data, not your code. Worth having if you work on iOS projects and want a triage system instead of guessing which debugging approach to try first.
