Subject: [PATCH] Add minimal nix development shell option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Refactor flake.nix to use shared commonBuildInputs for all shells
- Add minimalShell without Rust toolchain accessible via `nix develop .#minimal`
- Keep default shell with full Rust development environment
- Maintains backward compatibility while providing minimal shell option
