V8 Memory crash

[possan]

So, i'm trying to build and deploy vitebook to a subfolder on a cdn at every build of a project, but i keep hitting this issue.

I suspect it's a svelte ssr or maybe vite issue that but it's triggered by setting a baseUrl that is a few subdirectories down, but it also seems to be triggered by the filename length or depth of the path, maybe it's caused by the ssr prefetch step ending up in a endless loop recursing through the directories

Config from the svelte sample project with a baseUrl and vite base path added:

import { clientPlugin, defineConfig } from '@vitebook/client/node';
import { defaultThemePlugin } from '@vitebook/theme-default/node';

const BASEURL = '/xxxx/yyyy/zzzz/'

export default defineConfig({
  include: ['src/**/*.story.svelte'],
  plugins: [
    clientPlugin({ appFile: 'App.svelte' }),
    defaultThemePlugin(),
  ],
  vite: {
    base: BASEURL
  },
  site: {
    title: 'Sandbox Svelte4',
    description: '',
    /** @type {(import('@vitebook/theme-default/node').DefaultThemeConfig} */
    theme: {},
    baseUrl: BASEURL,
  },
});

Will crash with a OOM similar to this when i run a npm run vitebook:build:

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
 1: 0xb09980 node::Abort() [node]
 2: 0xa1c2[35](zzz:9:35) node::FatalError(char const*, char const*) [node]

 8: 0xebeeb0 v8::internal::Heap::CollectGarbage(v8::internal::AllocationSpace, v8::internal::GarbageCollectionReason, v8::GCCallbackFlags) [node]
...

But setting a shorter path seems to work fine

const BASEURL = '/x/y/z/'

It also seems to work ok when running npm run vitebook:dev except from a few small ui issues (menu seems to be missing).

This little patch seems to fix the build problems, but it still has some errors like that the index.html file redirecting to / instead of the specified baseUrl

@possan
Your fix seems to work perfectly. Could you create a PR? Would be amazing to have this issue solved.

I have created a patch for patch-package. Maybe this is useful for someone.
