E0320: Bad @ui.Island arguments

@ui.Island takes an optional path and strategy as string literals (the vuka command reads them from the source), then options: ui.Layout(…) and ui.Strategy("…"). It goes on a type. Reported by the build, vuka vet and, for what only shows at run time, at boot.

Wrong

@ui.Island(path, "load", "extra")
type Chart struct{ … }

Right

@ui.Island("charts/Revenue.vue", ui.Strategy("load"))
type Chart struct{ … }
