feat(ios): keep slider, picker, alert, list and navigation elements in ui dump

[gmegidish]

Summary

filterSourceElements kept only 10 iOS element types, so clients that map native types to semantic roles could never match most of them on iOS. In mobilewright, getByRole('slider'), 'list', 'listitem', 'tab', 'link', 'header' (and the new 'progressbar', 'alert', 'combobox' in mobile-next/mobilewright#332) found nothing unless the element carried an accessibilityIdentifier.

Newly accepted types:

Slider, ProgressIndicator, ActivityIndicator, Picker, PickerWheel, Link, Tab, TabBar, NavigationBar, Toolbar, Alert, Sheet, Cell, Table, CollectionView, ScrollView

• Slider, Picker, PickerWheel are always included even without a label, like TextField and Switch — they are interactive and often unlabeled.
• Everything else still needs a label / name / identifier, so unlabeled containers stay out and dumps stay small.
• Other is deliberately not added; it would flood the dump.

Behaviour change to review

A labeled container (Cell, NavigationBar, Alert, …) now appears in the dump with its children nested under it. Previously the container was dropped and its children hoisted to the nearest accepted ancestor. Unlabeled containers behave exactly as before.

Test plan

• go test ./devices/devicekit/ — 3 new tests (labeled role types kept, unlabeled adjustable controls kept, unlabeled containers still dropped with children hoisted)
• golangci-lint — same 8 pre-existing issues as main, none new
• Real iOS device / simulator smoke
• Confirm mobile-mcp copes with nested labeled containers

Summary by CodeRabbit

• New Features

  • Screen element trees now retain additional semantic-role elements, including links, tabs, navigation, toolbars, alerts, sheets, tables, collections, and scroll views.
  • Sliders, pickers, and picker wheels are retained even without identifiers.
  • Relevant labeled elements behind semantic roles are now preserved.

• Bug Fixes

  • Empty labels, names, identifiers, and placeholder values are correctly treated as absent.
  • Unlabeled containers remain filtered while their child elements are preserved.

📝 Walkthrough

Walkthrough

The source filter now accepts more semantic-role and container element types. It retains unlabeled sliders and pickers. Empty identifier values count as absent. Tests cover semantic-role mapping and child hoisting from anonymous containers.

Changes

Source Element Filtering

Layer / File(s)	Summary
Filter behavior and validation devices/devicekit/source.go, devices/devicekit/source_test.go	The filter accepts additional semantic-role and container types. Sliders, pickers, and picker wheels remain included without identifiers. Empty identifier values are treated as absent. Tests cover normalized semantic types and child hoisting from filtered containers.
