Summary

This PR implements Phase 13 of the LiveUI widget component migration, migrating data, document, feedback, and chart widgets to the widget component architecture established in Phase 11.

Sections

  • Phase 13.1 & 13.2 - Data and Feedback Widget Tests (56 tests)

    • Data widgets: list, table, tree_view, markdown_viewer, log_viewer
    • Feedback widgets: status, progress, gauge, inline_feedback
    • Chart widgets: sparkline, bar_chart, line_chart
  • Phase 13.3 - Integration Tests (12 tests)

Test Coverage

  • 68 total regression tests across all widget families
  • Tests verify widget boundaries, identity preservation, event semantics, and composition
  • Integration tests verify end-to-end widget composition in realistic screen scenarios

Key Changes

  • All data and feedback widgets now use the widget LiveComponent contract from Phase 11
  • Widget identity includes mode differentiation (native vs canonical) and path tracking
  • Event routing through widget boundaries is preserved
  • Widget-local state management is supported for interactive widgets

Test plan

  • Run all Phase 13 tests: mix test test/live_ui/data_widgets_test.exs test/live_ui/feedback_widgets_test.exs test/live_ui/phase_13_integration_test.exs
  • Verify widget boundaries are rendered with correct attributes
  • Verify widget identity is stable across renders
  • Verify event semantics are preserved for all widget types
  • Verify styling attributes propagate correctly

Split the monolithic Phase 13 into focused sections following
the same section-by-section pattern used in Phase 12:

- Phase 13: Data and Feedback Widget Component Migration
  (list, table, tree_view, markdown_viewer, log_viewer,
   status, progress, gauge, inline_feedback, sparkline,
   bar_chart, line_chart)

- Phase 14: Overlay, Operational, and Display Widget Component Migration
  (overlay_surface, dialog, alert_dialog, context_menu, toast,
   stream_widget, process_monitor, supervision_tree_viewer,
   cluster_dashboard, viewport, scroll_bar, split_pane, canvas)

- Phase 15: Canonical Renderer Convergence
  (retarget canonical rendering to widget component boundaries,
   remove renderer-only markup paths)

- Phase 16: Advanced Widget Integration Tests
  (cross-family composition, native/canonical parity)

- Renumber old Phase 14 to Phase 17: Tooling, Demo, Validation,
  and Release Readiness for Widget Components
Add regression tests for data and feedback widgets to verify they
preserve identity, styling, slots, and event semantics through
the widget component architecture.

**Phase 13.1 - Data and Document Widgets** (27 tests)
- List widget tests: component boundary, ordered mode, selection
- Table widget tests: component boundary, dense mode, row selection
- TreeView widget tests: component boundary, nested nodes, selection, expansion
- MarkdownViewer widget tests: component boundary, markdown rendering
- LogViewer widget tests: component boundary, log levels, wrap mode

**Phase 13.2 - Feedback and Chart Widgets** (29 tests)
- Status widget tests: component boundary, severity, status states
- Progress widget tests: component boundary, percentage, indeterminate
- Gauge widget tests: component boundary, ranges, value display
- InlineFeedback widget tests: component boundary, severities
- Sparkline widget tests: component boundary, data series (display family)
- BarChart widget tests: component boundary, data series (display family)
- LineChart widget tests: component boundary, data series (display family)

**Test Coverage:**
- Widget identity preservation across renders and modes
- Event semantics (click, selection, change)
- Bounded local state support
- Styling attributes (tone, variant)
Add end-to-end integration tests for Phase 13 widget migrations.
Verifies that data, document, and feedback widgets work correctly
together in realistic screen scenarios.

**Test Scenarios:**
- Data dashboard integration with status, table, and progress widgets
- Document viewer integration with markdown and log widgets
- Widget identity preservation across renders and modes
- Event routing through widget boundaries
- Styling propagation through feedback widgets
- Bounded local state support for data and feedback widgets

**Total Tests:**
- Phase 13.1: 27 data and document widget tests
- Phase 13.2: 29 feedback and chart widget tests
- Phase 13.3: 12 integration tests
- **Total: 68 regression tests**
