🛡️ Sentinel: [CRITICAL] Fix path traversal in list_files pattern

[mleem97]

🚨 Severity: CRITICAL
💡 Vulnerability: The pattern parameter in greg.io.list_files was passed unsanitized to Directory.GetFiles. This could be exploited to bypass the sandbox and list or interact with files outside the allowed data directory via path traversal (e.g., ../).
🎯 Impact: A malicious mod could enumerate and potentially access sensitive files anywhere on the system.
🔧 Fix: Added input validation for the pattern argument to prevent path traversal characters (.., /, \). Throws an UnauthorizedAccessException if malicious patterns are detected. Used .ToString() on separator characters to ensure cross-version .NET compatibility.
✅ Verification: Verified using local testing and ensuring the test suite passes.
