This commit introduces a Nix flake (flake.nix and flake.lock) to provide a reproducible development shell for NuttX using Nix and flakes. - Adds a devShell with all required build tools and dependencies for NuttX, including CMake, Ninja, GNU Make, clang-tools, ARM toolchain, and other utilities (automake, bison, flex, genromfs, gettext, gperf, kconfig-frontends, libelf, expat, gmp, isl, libmpc, mpfr, ncurses, zlib, kconfiglib). - Uses flake-utils to support multiple platforms. - Sets up a shell hook to enable CMake compile commands and provide a welcome message. - Based on nixpkgs `nixos-unstable` for up-to-date packages. Purpose: - Simplifies onboarding and ensures a consistent build environment across contributors. - Reduces "works on my machine" issues by pinning dependencies. Tested by running `nix develop` and building NuttX on x86_64-linux. No impact on runtime or target builds; this only affects developer tooling. For more details, see the new flake.nix file.
