xint-localhost-only-cannot-be-desktop-bridged-without-traefik

xint binds to 127.0.0.1:18207 (localhost only) and requires a Bearer token. Claude Desktop runs on macOS and has no network path to VPS localhost ports. Moving xint to Desktop connector requires: DNS record creation, Traefik file-provider route (not labels — xint is systemd not Docker), and Bearer auth header passthrough. Without this, xint must remain permanently registered on VPS.
