[bug\_fix] TS2304: Cannot find name 'process' / TS2580: Cannot find name 'require'.

Install '@types/node' as a devDependency, ensure tsconfig.json uses 'moduleResolution': 'node' \(or 'bundler' for modern setups\), and remove any explicit 'types' array that excludes 'node'.

Journey Context:
Developer initialized a new TypeScript project for a CLI tool using tsc --init. They wrote console.log\(process.env.PORT\) and immediately saw 'Cannot find name process'. They assumed TypeScript knew about Node.js globals automatically. They tried importing process from 'process', which failed at runtime because process is global. Searching StackOverflow, they found they needed @types/node. They ran npm install -D @types/node. The error persisted. They checked tsconfig.json and saw 'types': \['jest'\] which explicitly limited included types, excluding node. They removed the 'types' array entirely to auto-include all @types. They also noticed 'moduleResolution' was set to 'classic' \(from an old template\), which they changed to 'node'. After restarting the TS server, process and require were recognized. The fix works because TypeScript requires explicit declaration files for global environments; @types/node provides these declarations, and the compiler must be configured to resolve node\_modules/@types and include the node types in the compilation scope.
