Describe the Bug

So I was running npm run dev -- --host to start the devServer:

> astro dev --host

  🚀  astro  v1.9.1 started in 839ms
  
  ┃ Local    http://localhost:3001/
  ┃ Network  http://192.168.2.66:3001/

             http://169.254.164.104:3001/

And I was able to access url like http://192.168.2.66:3001/.

Then I made a change to my tailwind.config.cjs file, saved the file and I can saw the terminal updated with logs:

06:35:17 PM [astro] update /tailwind.config.cjs
06:35:17 PM [astro] Configuration updated. Restarting...

Now I can no longer access http://192.168.2.66:3001/ while I was still able to open http://localhost:3001/.

I can see config.server.host set to true in the beginning,

But It was reset to false after restart:

Thanks for opening an issue! Definitely seems like a bug in our restart logic, but it does look like we're passing CLI arguments through correctly.

I wonder if this is just an issue with how we're displaying the message? Happy to review a PR if you want to look into this more!

I believe that flags comes from https://github.com/withastro/astro/blob/main/packages/astro/src/core/dev/dev.ts#L38 which is always an empty {}.
