Currently our subdomain app URLs are: - `<port>--<agent>--<workspace>--<username>` - `<app>--<agent>--<workspace>--<username>` App names are already unique per template, enforced at the provisioner level. The second format can most likely be changed to allow for `<app>--<workspace>--<username>` to save URL space. Relates to https://github.com/coder/coder/issues/15178, as it'll help make URLs smaller
