iOS CI/CD: merge to main

iOS CI/CD: merge to main ships TestFlight — I built a production-style iOS pipeline: SwiftLint, unit tests, and a coverage gate on every PR; on merge to main the app is signed and uploaded to TestFlight. The public repo runs this pipeline on itself with green GitHub Actions runs you can inspect. This is the same $499 install I sell: one PR, async, no calls. https://github.com/lamtalaa/CICDPipelinePOC
