Safer Node.js Buffer API Polyfill

safe-buffer is a JavaScript library that provides a consistent and safer API for Node.js `Buffer` operations, particularly for older Node.js environments. It backports the modern `Buffer.from`, `Buffer.alloc`, and `Buffer.allocUnsafe` methods, which address security and stability concerns related to uninitialized memory in older `new Buffer(size)` constructors. For Node.js versions where these safer methods are natively available (v6.0.0 and above), `safe-buffer` transparently defers to the built-in implementation, acting as a compatibility layer. The current stable version is 5.2.1, with releases being infrequent given its role as a polyfill for established Node.js core APIs, with the last major update occurring approximately 6 years ago. Its primary differentiator is ensuring safe `Buffer` allocation across a wide range of Node.js versions without requiring conditional logic in application code.
