🛡️ Sentinel: [CRITICAL] Fix Path Traversal in greg.io.list_files

[mleem97]

🚨 Severity: CRITICAL
💡 Vulnerability: The Directory.GetFiles call in greg.io.list_files within GregIoLuaModule.cs directly accepted user-provided pattern input without validating it for path traversal sequences like ../. This allowed malicious Lua scripts to escape the sandbox (dataDir) and enumerate files anywhere on the file system that the process had access to.
🎯 Impact: Malicious actors could discover and enumerate the presence and structure of sensitive files and directories on the host server or player's machine, outside the intended Mod directory scope.
🔧 Fix: Added explicit validation to the pattern argument to throw an UnauthorizedAccessException if it contains .., Path.DirectorySeparatorChar, or Path.AltDirectorySeparatorChar.
✅ Verification: Verified compilation and no regressions via dotnet test using DOTNET_ROLL_FORWARD=Major. Verified .jules/sentinel.md journal is properly updated.
