feat(wisdom): add vscode editor module

Add a new module for Visual Studio Code configuration including
default extensions (nix-ide, markdown-all-in-one, prettier) and
nixd/nixfmt settings. Enable vscode on 14900k, t2mbp, and uConsole
hosts with additional extensions.

Also clean up unfree predicate logic in ideapad configuration.
