Tutorial: powershell

This project serves as a secure PowerShell analysis bridge for Node.js, designed to safely interpret and classify user commands. It spawns a native pwsh process to parse scripts into a structured Abstract Syntax Tree (AST), which is then normalized into typed objects. The system uses this structured data to detect security patterns (like injection risks), validate against a registry of dangerous cmdlets, and generate least-privilege permission suggestions for the user interface.
