fix: css import in tanstack-start example

[s-r-x]

in production build the start injects 2 css urls: 1 for the server build and 1 for the client one. the base urls are different, so, apparently, the server link is broken. the same happens to every asset imported with ?url, not only css.

there's an open PR, but it doesn't look like it's gonna be merged anytime soon.

📝 Walkthrough

Walkthrough

The root route now imports styles.css as a side effect instead of importing it as a stylesheet URL. Its head() configuration no longer injects the stylesheet through a <link rel="stylesheet"> entry.
