feat(esm): add 'module.exports' export hint for Node.js ESM/CJS interop

Add `export { x as 'module.exports' }` to all default exports as a hint
for Node.js ESM/CJS interoperability. This documents the intended interop
behavior even though frozen objects still require .default accessors at
runtime.
