iOS Simulator

Use Apple's xcrun simctl for lifecycle and app operations, and current idb for accessibility/input. Keep native command syntax rather than a second simulator API. Resolve SKILL_DIR to the directory containing this file; it is not the app repository's scripts/ directory.

Establish the target

xcode-select -p
xcodebuild -version
xcrun simctl list --json
idb --help
idb list-targets
