Xcode Build Fixer

This is the implementation companion to xcode-build-orchestrator. Once you've got an approved optimization plan, this skill applies the changes one at a time, then re-benchmarks to verify the delta. It handles build settings (like switching to dwarf debug symbols or enabling compilation caching), script phase guards, source-level compilation fixes (type annotations, breaking up complex expressions), and SPM restructuring. The revert logic is nuanced: it knows that certain Apple-recommended settings like COMPILATION_CACHE_ENABLE_CACHING should stay even if the initial benchmark shows no win, because they compound over real workflows. Speculative changes get reverted if they regress. Good if you want to stop guessing at build fixes and actually measure what works.
