The agentsdk currently does a remap of the DERP map to change the EmbeddedRelay node's URL to match the agent's access URL. This PR makes changes to the `workspacesdk` (used by clients like the CLI) and `vpn` (used by Coder Desktop) to match this behavior. This enables us the ability to try Coder clients in dogfood over a VPN without changing the global access URL.
