E0311: Island component is ambiguous

A bare @ui.Island found more than one file for the type (islands/Chart.vue and islands/Chart.tsx), and the extension decides the framework, so vuka won't guess.

Wrong

// web/islands/Chart.vue and web/islands/Chart.tsx both exist
@ui.Island
type Chart struct{ Series []float64 }

Right

@ui.Island("islands/Chart.vue")
type Chart struct{ Series []float64 }
