Ensure correct order of inference sensitive properties for createRoute functions

For the following functions, the property order of the passed in object matters due to type inference:

createRoute
createFileRoute
createRootRoute
createRootRouteWithContext

The correct property order is as follows

params, validateSearch
loaderDeps, search.middlewares, ssr
context
beforeLoad
loader
onEnter, onStay, onLeave, head, scripts, headers, remountDeps

All other properties are insensitive to the order as they do not depend on type inference.

Rule Details

Examples of incorrect code for this rule:

src/routes/path.tsx

/* eslint "@tanstack/router/create-route-property-order": "warn" */
import { createFileRoute } from '@tanstack/react-router'

export const Route = createFileRoute('/path')({
  loader: async ({ context }) => {
    await context.queryClient.query({
      ...getQueryOptions(context.hello),
      staleTime: 'static',
    })
  },
  beforeLoad: () => ({ hello: 'world' }),
})
