Mobile CI Pipeline Skill

Generate CI/CD pipeline configurations for Android and iOS mobile apps. Use this skill whenever the user asks to: set up GitHub Actions for a mobile app, configure Bitrise, set up GitLab CI for Android/iOS, write a Fastfile for mobile, configure Fastlane for iOS or Android, set up automated builds, automate TestFlight uploads, automate Play Store uploads, set up code signing in CI, configure Fastlane Match, set up Firebase App Distribution, automate APK/AAB signing, configure build variants in CI, set up Gradle caching in CI, handle iOS provisioning in CI, or write a README for a mobile CI pipeline. Also triggers for: "automate my mobile releases", "how do I deploy to TestFlight automatically", "set up CD for my Android app", "configure signing for CI", "generate a Fastlane setup", "set up build matrix for Android". Do NOT use for generating app code, debugging, or testing setup (use mobile-testing-suite for tests).
