VS Code Extension for Inline Security Warnings

[dagangtj]

Overview

This PR implements a VS Code extension that provides real-time security scanning with inline warnings for AI agent code.

Closes #6

Features Implemented

✅ VS Code Extension

• Real-time scanning using isnad-scan patterns
• Inline warning decorations for flagged dependencies
• Hover tooltips with risk details and ISNAD attestation status
• Configuration for scan sensitivity levels
• Status bar indicator showing current file security status

✅ Core Functionality

• Automatic scanning on file open, save, and change (configurable)
• Manual commands: ISNAD: Scan Current File and ISNAD: Scan Workspace
• Supports JavaScript, TypeScript, and Python files
• VS Code diagnostics API integration

✅ Security Patterns Detected

• Code execution (eval, exec, spawn)
• Data exfiltration (dynamic fetches, webhooks)
• Credential access (env vars, sensitive files)
• File system abuse (system directory writes)
• Network issues (raw sockets, DNS exfiltration)
• Obfuscation techniques
• Security bypasses
