So wgengine/router is just the docs + entrypoint + types, and then underscore importing wgengine/router/osrouter registers the constructors with the wgengine/router package. Then tsnet can not pull those in. Updates #17313 Change-Id: If313226f6987d709ea9193c8f16a909326ceefe7 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
