typescript, javascript: index Vue single-file components - #1738

A .vue file was never read, so a helper called only from a template had no caller and a component rendered only by a template had no use. Each .vue component is now read as a virtual script that keeps every line: its inline <script>/<script setup> bodies verbatim, plus one top-level statement per template reference (<Child/> and <my-child> as calls, @event handlers as calls or statements, bound expressions and {{ }} as expressions). lang=ts/tsx goes to the TypeScript analyzer, a JavaScript script to the JavaScript one; a component with no inline script is not analysed. tsconfig include globs claim .vue files and relative ./X.vue imports resolve to the component.
