Adds the real MoonWatch implementation on top of the initial Xcode template: new SwiftUI views (MoonDiskView, StarFieldView), the MoonWatchWidget extension, and a Shared module containing the moon phase calculator, shadow shape, and shared asset catalog. Also adds a Swift/Xcode/macOS .gitignore and untracks per-user xcuserdata files. Co-authored-by: Cursor <cursoragent@cursor.com>
