[bug\_fix] gyp ERR\! build error

Install Python 3 and Visual Studio Build Tools \(Windows\) or Xcode Command Line Tools \(macOS\), then set npm config python/python3 paths if needed.

Journey Context:
Developer on Windows clones a repo and runs npm install. It fails during compilation of a native addon \(like bcrypt, sqlite3, or sharp\). The error log shows gyp ERR\! build error followed by Cannot find Python or MSBuild.exe not found. The developer tries installing random Python versions from python.org which doesn't work because node-gyp requires specific Python 3.x and Microsoft Visual C\+\+ compiler. They try npm install --global windows-build-tools \(deprecated\) which hangs. The root cause is that node-gyp \(Node's native addon build tool\) requires a C\+\+ compiler and Python to compile native modules. On Windows, the reliable fix is to install Visual Studio 2022 Build Tools with the "Desktop development with C\+\+" workload, and ensure Python 3 is installed and available in PATH. Then configure npm: npm config set python python3. On macOS, installing Xcode Command Line Tools \(xcode-select --install\) suffices.
