 * Node.js CLI Argument Parser - Rust Implementation
 *
 * This is a Rust implementation that matches the exact behavior of
 * Node.js CLI argument parsing found in src/node_options.cc and related files.
 *
 * Based on Node.js source code analysis of:
 * - src/node_options.cc (option definitions and parsing logic)
 * - src/node_options.h (option structures and types)
 * - src/node_options-inl.h (template implementation)
 * - src/node.cc (main execution flow)
