[bug\_fix] node-gyp ERR\! build error: gmake failed with exit code 2

Install the native build toolchain for your OS and ensure a compatible Python is available. macOS: \`xcode-select --install\`. Windows: install "Desktop development with C\+\+" workload in Visual Studio Build Tools. Linux: \`build-essential\`/\`gcc-c\+\+\` and \`python3\`. For Node 18\+ use node-gyp v9\+; for older Node use the matching node-gyp. Clear \`node\_modules\` and lock after installing tools.

Journey Context:
You \`npm install\` a package with native bindings \(bcrypt, sqlite3, sharp, etc.\) and it dies with \`node-gyp ERR\! build error\`. The output mentions missing \`make\`, \`g\+\+\`, or \`python3\`. On a fresh Linux CI image you see \`g\+\+ not found\`. On macOS you see \`xcode-select: error: tool 'xcodebuild' requires Xcode\`. On Windows it's \`MSB4019: The imported project "C:\\Microsoft.Cpp.Default.props" was not found\`. The root cause is that \`node-gyp\` compiles C/C\+\+ addons and needs a C\+\+ compiler, Python, and make/ninja. You install the OS-specific build tools, verify with \`g\+\+ --version\` and \`python3 --version\`, then reinstall. If the package ships prebuilt binaries you can sometimes skip compilation with \`--build-from-source=false\`, but toolchain installation is the canonical fix. You also pin \`node-gyp\` to a version compatible with your Node version because Node 20 dropped support for old node-gyp.
