chore: Significantly restructure folder layout r/237
This moves the various projects from "type-based" folders (such as "services" or "tools") into more appropriate semantic folders (such as "nix", "ops" or "web"). Deprecated projects (nixcon-demo & gotest) which only existed for testing/demonstration purposes have been removed. (Note: *all* builds are broken with this commit)
