npm install inside install_node_deps() builds native addons (e.g. node-pty) via node-gyp, which needs a C/C++ compiler. That was never checked, so a missing g++ only surfaced as a generic "npm install failed or timed out" deep inside npm's own output — and because install_node_deps failing short-circuits the rest of main() via `|| return`, users end up with no `hermes` command and no clue why.
