Documents moving the repo from Windows/other dev machines to macOS and
driving a real iPhone end-to-end via Appium + WebDriverAgent: Xcode/Appium
toolchain setup, WDA signing (using the extra_capabilities passthrough
already supported by WDADriverConfig), minimal real-device verification,
and starting a Runtime API that explicitly registers and connects the
device (neither the Console nor REST API currently expose a
connect/disconnect endpoint). Also covers multi-device port allocation,
common failure modes, and a completion checklist. README gains a pointer
to it under a new "Operator Guides" section.
