Xcode Build Benchmark

This does one thing well: it runs repeatable Xcode build benchmarks so you have numbers before you start optimizing. It measures clean builds, cached clean builds (when compilation cache is on), zero-change builds to find fixed overhead, and optional incremental builds with a file touch. Everything gets run three times and saved to timestamped JSON in `.build-benchmark/` so you can compare before and after. The workflow is opinionated about consistency, it won't modify your project files, and it explicitly stops after measuring unless you ask for optimization help. If your build times feel slow but you don't have a baseline, start here.
