More trimming of underused `explore` functionality. The `explore` command has subcommands that can be run like `:config` or `:try` or whatnot. This PR removes the `:config`, `:show-config`, and `:tweak` commands which are all for viewing+modifying config. These are interesting commands and they were cool experiments, but ultimately I don't think they fit with our plans for a simplified `explore`. They'd need a lot more polish if we want to keep them and I don't think we do. Happy to discuss if I've missed a good reason to keep these. cc @fdncred
