Make deletions through the Project Explorer archived in UserData, and un/redoable

[franknoirot]

Thanks @nadr0 for all the help thinking about this.

1. Introduces an "archive" path within the Electron "userData" location.
2. Creates a new window.electron.move() function that uses fs.rename to move files to and from this archive when deleting and restoring, with fallback behaviors
3. Wires up new systemIOMachine workflows recursiveMove and recursiveMoveAndNavigate (created by mostly miming deleteFileOrFolder)
4. Swaps out deletion workflows in ProjectExplorer for archive ones
5. Adds a new fsEffectExtension to CodeMirror which makes these archive workflows reversible using it's awesome invertedEffects Facet

Gonna mark this as draft until I can get some unit and E2E tests together next week.

wow this is dope! This makes me think it would be cool to have a trash bin in the app. Will be appreciated by the web users.

@max-mrgrsk yeah once we have web FS landed hooking this up to it will be pretty trivial. Then we can provide a way for users, whether desktop or web, to browse their archive and restore lost files.
