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

[mleem97]

Severity: CRITICAL
Vulnerability: Path Traversal (CWE-22) in src/Infrastructure/Scripting/Lua/Modules/GregIoLuaModule.cs. The list_files function directly passed a user-controlled pattern argument to Directory.GetFiles(). By supplying a pattern like ../*.*, an attacker could escape the sandboxed dataDir and list arbitrary files on the system.
Impact: An attacker could exploit this to list sensitive files outside of the intended sandbox directory, leading to information disclosure.
Fix: Added validation to the pattern argument in list_files to throw an UnauthorizedAccessException if it contains path traversal characters (.., /, \). Added inline comment // [Security] Prevent path traversal via pattern in Directory.GetFiles.
Verification: Ran dotnet test to ensure all tests pass. Tested locally using a temporary console app to verify that Directory.GetFiles is indeed vulnerable to path traversal via the search pattern and that rejecting patterns with .. prevents it.
