Adopt root-level tsswift app layout

Move the app payload under swift/ while keeping git, package.json, and .smartconfig.json at the repo root. This standardizes the Swift app setup so build, test, run, and watch workflows match the other repos.

 ## Open the project
 
-1. Open [IDPGlobal.xcodeproj](/Users/philkunz/gitea/idp.global-swiftapp/IDPGlobal/IDPGlobal.xcodeproj).
+1. Open `swift/IDPGlobal.xcodeproj`.
 2. Build the `IDPGlobal` scheme for:
    - `My Mac`
    - an iPad simulator
    - an iPhone simulator
 3. Build the `IDPGlobalWatch` scheme for an Apple Watch simulator when you want to verify the companion experience.
 
+## tsswift workflow
+
+From the repo root:
+
+```bash
+corepack pnpm install
+corepack pnpm swift:doctor
+corepack pnpm swift:emulators
+corepack pnpm swift:build
+corepack pnpm swift:test
+corepack pnpm swift:run
+corepack pnpm swift:watch
+```
+
+This repo now follows the same layout as the other Swift app repos:
+
+- git root at the repo root
+- root `package.json`
+- root `.smartconfig.json`
+- Swift app content under `swift/`
+
+Current `tsswift` behavior here:
+
+- `build` targets macOS, iPhone Simulator, and iPad Simulator in parallel
+- `test` targets macOS
+- `run` defaults to macOS unless you pass `--platform ios` or `--platform ipad`
+- `watch` rebuilds and relaunches macOS, iPhone, and iPad app instances on file changes
+
+The Apple Watch companion is still part of the Xcode project, but `tsswift` is currently configured around the main `IDPGlobal` app targets only.
