This PR adds a minimal Nix flake to provide a development environment for building Grapesy. The flake sets up the necessary native dependencies (snappy, protobuf, zlib) along with Haskell development tools. Why this approach? === I've chosen to use a simple mkShell rather than more sophisticated Haskell packaging approaches like haskell.nix for several reasons: The snappy-c Haskell package currently has build issues in nixpkgs master This configuration focuses solely on providing native dependencies needed for successful builds The approach keeps compatibility with non-Nix development workflows The flake provides all necessary tools for development without introducing complex Nix dependencies that might be unfamiliar to many Haskell developers. What it provides === GHC and cabal-install Haskell Language Server Native libraries: snappy, protobuf, zlib pkg-config for library detection This should make it easy for Nix users to get started with Grapesy development with a simple nix develop. I use with direnv.
