🛡️ Sentinel: [CRITICAL] Fix path traversal in Directory.GetFiles search pattern

[mleem97]

🚨 Severity: CRITICAL
💡 Vulnerability: The pattern argument in Directory.GetFiles within GregIoLuaModule.cs was not validated, allowing arbitrary file system enumeration by passing path traversal sequences (like ..\\) through the Lua sandbox.
🎯 Impact: An attacker or malicious mod script could enumerate and list the contents of arbitrary directories on the host machine, bypassing the intended sandbox.
🔧 Fix: Added input validation for the pattern parameter to block strings containing .., /, or \, effectively neutralizing directory traversal attempts and enforcing the sandbox bounds.
✅ Verification: Manual testing was performed with dummy paths to confirm GetFiles behavior. The patch application and .NET test suite verify functionality remains intact.
