fix(rollup): enable interop:auto on server CJS bundle

Several CJS deps (koa-body@7, p-queue@6) ship modules whose runtime
require() result is a namespace { default: fn, ... } rather than the
function/class itself. Without rollup's interop wrapper, default
imports like `import PQueue from 'p-queue'` were compiled to
`var PQueue = require('p-queue')` and then `new PQueue(...)` was
called on the namespace object, throwing TypeError at server boot
and on socket events.

Setting output.interop to 'auto' restores the _interopDefault wrapper,
so default imports access X__default.default at call sites. This
future-proofs other CJS deps with the same export shape (Koa, Router,
cors, http, https) which the auto interop now also wraps.
