React2shell Indicators from Node/Next Processes on Web Servers

Detects indicators of React2shell exploitation originating from 'node' or 'next' processes on web-facing or internet-facing assets. This rule identifies suspicious network connections to common web ports (3000, 8080, 443, 80) or process executions containing command-line arguments indicative of prototype pollution exploitation (e.g., '__proto__', 'constructor:constructor', 'process.mainModule.require', 'execSync', 'vm.runInThisContext', 'fs.readFileSync') or common post-exploitation commands ('whoami', '/etc/passwd', 'id', 'env', 'hostname').
