Describe the bug

The prerender option without a sitemap throws this error:

error during build:
Error: Sitemap is not enabled
    at buildSitemap (file:///Users/jan/code/privat/tests/prerender-no-sitemap/node_modules/@tanstack/start-plugin-core/dist/esm/build-sitemap.js:75:11)

tanstack start 1.134.6, seem like it doesn't respect prerender setting in vite.config.ts vite.config.ts

    tanstackStart({
      prerender: {
        enabled: false,
      },
      spa: {
        enabled: true,
        prerender: {
          // ?? must enable this to get loader context working??
          enabled: false,
        },
      },
      sitemap: {
        enabled: false,
      },
    }),
    nitro({
      config: {
        preset: 'node-server',
        compatibilityDate: 'latest',
      },
    })

vite build output:

Same thing for:

    "@tanstack/solid-router": "1.139.3",
    "@tanstack/solid-start": "1.139.3",

[elite174]

My config:

    tanstackStart({
      prerender: {
        enabled: false,
      },
      sitemap: {
        host: "http://localhost:3000",
      },
      spa: {
        enabled: true,
        prerender: {
          enabled: false,
        },
      },
    }),

Result config used during the build:

{
  srcDirectory: 'src',
  start: {},
  router: {
    target: 'solid',
    routeFileIgnorePrefix: '-',
    routesDirectory: '...',
    quoteStyle: 'single',
    semicolons: false,
    disableLogging: false,
    routeTreeFileHeader: [
      '/* eslint-disable */',
      '// @ts-nocheck',
      '// noinspection JSUnusedGlobalSymbols'
    ],
    indexToken: 'index',
    routeToken: 'route',
    generatedRouteTree: '...',
    disableTypes: false,
    addExtensions: false,
    enableRouteTreeFormatting: true,
    tmpDir: '...',
    importRoutesUsingAbsolutePaths: false,
    basepath: ''
  },
  client: { base: '/_build' },
  server: {},
  serverFns: { base: '/_serverFn' },
  pages: [ { path: '/', prerender: [Object], sitemap: [Object] } ],
  sitemap: {
    enabled: true,
    host: 'http://localhost:3000',
    outputPath: 'sitemap.xml'
  },
  prerender: { enabled: true },
  spa: {
    enabled: true,
    maskPath: '/',
    prerender: {
      outputPath: '/_shell',
      crawlLinks: false,
      retryCount: 0,
      enabled: true
    }
  }
}

Why? It's different?

commented enabled: true - it worked

Still the result is SSR, no HTML file in dist folder.
