feat: surface enabled, selected and focused attributes from ios ui dump

[gmegidish]

Summary

• Parse the new enabled, selected and hasFocus attributes emitted by devicekit-ios and map them onto ScreenElement (hasFocus → focused), matching the fields already populated on Android
• Attributes are pointers and omitted when absent, so output is unchanged for older agents

Test plan

• TestFilterSourceElementsPreservesStateAttributes covers the mapping
• Verified end-to-end on a simulator with the Playground app (Basic UI): focused text field, disabled button and selected segment all reported

Requires devicekit-ios release with mobile-next/devicekit-ios#69 (agent version bump will follow separately).

Summary by CodeRabbit

• New Features

  • Screen elements now preserve enabled, selected, and focused states when reported by the device.
  • Focus information is supported for iOS elements that provide focus status.

• Documentation

  • Updated focus-state documentation to clarify platform support.

• Tests

  • Added coverage for preserving element states and handling missing state attributes.
