ios: fix keyboard behavior

 - `just build` will:
   1. generate `Sybil.xcodeproj` with `xcodegen` if missing,
   2. build scheme `Sybil` for `iPhone 16e` simulator.
+- Preferred test command: `just test`
+- `just test` runs the Swift package tests through `xcodebuild test` on the `iPhone 16e` iOS simulator from `ios/Packages/Sybil`.
+- `just test` disables Xcode parallel testing because the current async view-model tests use timing-sensitive selection tasks.
+- Do not use plain `swift test` for this package; it runs as host macOS and hits a deployment mismatch with `MarkdownUI`.
 - If `xcbeautify` is installed it is used automatically; otherwise raw `xcodebuild` output is used.
 
+## Simulator Workflow
+- Run the app in the simulator with `just run` from `/Users/buzzert/src/sybil-2/ios`.
+- `just run` boots the `iPhone 16e` simulator if needed, builds with a stable derived data path, installs `Sybil.app`, and launches bundle id `net.buzzert.sybil2`.
+- Capture a simulator screenshot with `just screenshot` from `/Users/buzzert/src/sybil-2/ios`; it writes `build/sybil-screenshot.png` by default.
+- To choose a screenshot path, run `just screenshot path=build/name.png`.
+- The underlying screenshot command is `xcrun simctl io booted screenshot <path>` and requires a booted simulator.
