"""Comprehensive execution tests for TUI module - targeting 100% code coverage.

Tests actual code execution paths for:
- All 4 TUI apps (graph, browser, dashboard, dashboard_compat)
- All 6 TUI widgets (graph_view, conflict_panel, view_switcher, item_list, state_display, sync_status)
- Storage adapter

Focus: Full lifecycle tests, action handlers, rendering, callbacks, reactive updates.
