[tooling] Project dependency conflicts with system packages or inconsistent development environments across team machines

Create a \`flake.nix\` with \`nix develop\` or legacy \`shell.nix\` with \`nix-shell\`, specifying exact versions of compilers, runtimes \(Node, Python, Rust\), and tools. Enter the environment with \`nix develop\`—tools are available only in this shell, isolated from the host system.

Journey Context:
Docker is heavy for local development; language version managers \(nvm, pyenv\) don't handle native libraries or system tools. Nix provides deterministic, reproducible, and composable environments using a pure functional package manager. It caches build outputs, allows temporary environments without installation, and ensures 'works on my machine' becomes 'works in this nix shell'.

environment: Unix-like systems \(Linux, macOS\), development environments · tags: nix nix-shell nix-develop reproducible environment dependencies · source: swarm · provenance: https://nixos.org/manual/nix/stable/command-ref/nix-shell.html
