Subject: [PATCH] fix(js,ts): of several `export default` lines, the one that
 names a node is the module's

A template can hold statement-shaped text: react.dev's
SandpackWithHTMLOutput.tsx writes two sandbox files' `export default
function` lines above its own `export default memo(function ...)`, and
reading only the first line left the module's default import with
nothing. Every line-initial statement outside a block comment is now
read, the first that names a node wins, and a function or class a
statement declares binds only the node that starts there, so a
template's `export default function formatHTML` can't reach the file's
real formatHTML. The block-comment check reads the file once for all of
its statements.

Carries #2432's default-export tests unchanged (all pass), and adapts
its multi-statement and declaration-position rules.

+ * `Vans` to `loader`: the route `/vans` rendered the loader, and every call
