Change the internal selected field from usize to Option<usize> so that an empty dashboard correctly reports no selection (None) instead of returning 0 pointing to nothing. - Change selected field from usize to Option<usize> - Default state uses None, new() uses Some(0) when widgets exist - selected_index() now returns Option<usize> - selected_position() now returns Option<(usize, usize)> - Update all navigation logic to wrap/unwrap Option - Update view() to use Option comparison - Update all test assertions to expect Some(value) - Add test_empty_dashboard_selected_index_is_none test Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

All other Envision components return
Option<usize>from their index methods. MetricsDashboard was the outlier returning a bareusize. When the widgets vec was empty,selected_index()returned0which was misleading.Test plan
