Adding "www." to the start of the url breaks the platform

[Torantulino]

If you go to https://www.platform.agpt.co/ instead of https://platform.agpt.co/ , the platform will not work at all. You won't be logged in even through you're logged in usually.
You can log in, but wont see any Agents in your library.

Steps to reproduce:

1. Go to https://www.platform.agpt.co/
2. Observe that you are logged out - log back in
3. Go to your library
4. Observe that you have no Agents in your library - even if you did before.

Desired Behaviour

https://www.platform.agpt.co/ and https://platform.agpt.co/ are the same website, rather than duplicate pages.

There should be no difference between them, they should both work, and you should be logged in no matter which url you type in.

---

Ahrefs is also showing these as "Duplicate pages without canonical" which is hurting our SEO.

I think that could be the case for the reverse proxy or by adding CNAME for the https://www.platform.agpt.co/ to https://platform.agpt.co/. By doing that hitting https://www.platform.agpt.co/ will just redirect user to https://platform.agpt.co/.
