Which project does this relate to?

Router

Describe the bug

When @tanstack/router-plugin auto code splitting is enabled, the transform crashes if any route sets errorComponent to null or false.

Type definitions allow this (errorComponent?: false | null | ErrorRouteComponent), but the code-splitter fails with:

Error: Unexpected splitNode type ☝️: BooleanLiteral
    at .../@tanstack/router-plugin/src/core/code-splitter/compilers.ts:621:21
    at Set.forEach (<anonymous>)
    ...

Steps to Reproduce the Bug or Issue

1. Open terminal
2. Run npm run build

Expected behavior

The plugin should gracefully handle booleans/nulls

Additional context

I'm setting errorComponent to null to handle all errors in my app using only defaultErrorComponent.
