Xcode Project Setup

This handles the messy parts of adding Swift Package Manager dependencies to Xcode projects without touching Ruby or manually editing pbxproj files. It bundles a Swift script that adds packages and links their products to your target in one shot, which is especially useful for Firebase setup since it auto-injects the ObjC linker flag that prevents those cryptic nil crashes. You point it at your xcodeproj, pass a repo URL and version, list the products you want, and optionally attach a plist like GoogleService-Info. The big win is it handles both adding the dependency and wiring up the frameworks phase, which normally requires clicking through Xcode's UI. Works on macOS with Swift installed, and it's smart enough to skip things already configured.
