feat: include enabled, selected and focused state attributes in json ui dump

[gmegidish]

Summary

• Emit enabled (only when false), selected and hasFocus (only when true) in the json ui dump, keeping the tree small
• Keep an unreported enabled attribute as unknown instead of defaulting to false
• Resolve keyboard focus with a hasKeyboardFocus == true predicate query (same approach as WebDriverAgent) and stamp the matching node — the snapshot's hasFocus attribute is the tvOS focus engine and is always false on iPhone/iPad

Test plan

• Verified on simulator with the Playground app (Basic UI): focused text field reports hasFocus: true, disabled button reports enabled: false, active segment reports selected: true

Walkthrough

The change preserves unknown enabled values when XCTest omits the attribute. SourceTreeElement emits explicit enabled, selected, and focused states. getAppViewHierarchy queries the focused XCTest element, converts its frame to an AXFrame, and applies keyboard focus recursively to matching AXElement nodes. No focus state is added when the query finds no matching element.

Merge Risk: 🔵 Low · up to c50d6

The PR is mergeable with explicit owner follow-up for a bounded correctness risk: in some hierarchies, more than one JSON node could be reported as focused when nodes share the same frame.

assignment to identify the queried element using stable element identity rather
than matching frame alone, or stop traversal after selecting the first match.
Ensure containers sharing a frame with the focused descendant are not both
marked focused, so the JSON contains exactly one focused element.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not mark every node with the matching frame.

If a container and its focused descendant share the same frame, this traversal sets hasFocus to true on both nodes. Match a stable element identity from the query, or stop after selecting one node, so the JSON contains one focused element.
