v0.3.1

Two fixes to the listing, both found with the \k command of usql.

The server and the worker of authentik, whose image is ghcr.io/goauthentik/server, no longer list as SQL Server, and a lookup of them no longer tries to connect as SQL Server. SQL Server now matches only an image under an mssql path, such as mcr.microsoft.com/mssql/server.

A CloudNativePG Database with the name of its cluster no longer lists as a second row whose URL reached the cluster. A Database that opens the database of its cluster folds into the cluster's row, and one that opens another database gets a URL through its cluster with the database in the path, such as k://photos.prod/pics. A cluster's row lists the database of each of its Databases.
