Move all global configuration into config folder as defined by the xdg basedir spec

[airtonix]

It's a bit annoying that some of the global configuration is in the vscode directory deeply deeply nested somewhere in the users homedir unpredictable.

https://specifications.freedesktop.org/basedir-spec/latest/

Instead it should just be collected under the standard xdg base dir spec of

~/.config/kilocode

You can use any xdg base dir library to manage discovering these places, but probably just use https://www.npmjs.com/package/xdg-basedir
