Added

Add support for Nix Flakes. Lorri will still prefer a shell.nix by default, but if overridden or only a flake.nix is available, Lorri will build a flake and use its default devShell.
Delegate adding roots to the nix-daemon. This improves a number of use cases, especially for new users.
Improvements to the watcher code, including smoother debounce of filesystem events. This provides more reliable builds, and fewer unneeded ones.
Better output from lorri info, including information about the project, and details about how lorri is running.
