Hostname considerations:
- Workspace names, usernames, and agent names can't have double hyphens, so this name can't conflict with a real Coder Connect hostname.
- Components can't start or end with hyphens according to [RFC 952](https://www.rfc-editor.org/rfc/rfc952.html)
- DNS records can't have hyphens in the 3rd and 4th positions, as to not conflict with IDNs https://datatracker.ietf.org/doc/html/rfc5891
