Default Build Script Order Breaks CI/CD When routeTree.gen.ts is Gitignored

[danielo515]

The default template generated by npm create @tanstack/start@latest sets the typechek script to just execute tsc. This causes failures in CI/CD pipelines when routeTree.gen.ts is gitignored because the file is generated by the Vite plugin during the build, but type checking often runs before or as part of the pipeline.

Since the TypeScript compiler runs before the Vite build in many setups, it fails due to the missing generated file, even though the Vite plugin would create it moments later.

Expected Behavior: The starter template should either:

1. Adjust the default typecheck script to vite build && tsc --noEmit to ensure generation happens first, or
2. Include a pre-build step using tsr generate to create the file before type checking.
   This would make the default template more robust for CI/CD environments without requiring manual configuration.
3. Have a dedicated typecheck:ci and avise to use it in CI
