Adds 13 security tests across 4 files for hardening verification: **Path Traversal Tests (path_traversal_test.go):** - TestSecurePathValidator_ValidRelativePath - TestSecurePathValidator_PathTraversalBlocked - TestSecurePathValidator_SymlinkEscape - Tests symlink resolution and path boundary enforcement **File Type Validation Tests (filetype_test.go):** - TestValidateFileType_AllowedTypes - TestValidateFileType_DangerousTypesBlocked - TestValidateModelFile - Tests magic bytes validation and dangerous extension blocking **Secrets Management Tests (secrets_test.go):** - TestExpandSecrets_BasicExpansion - TestExpandSecrets_NestedAndMissingVars - TestValidateNoPlaintextSecrets_HeuristicDetection - Tests env variable expansion and plaintext secret detection with entropy **Audit Logging Tests (audit_test.go):** - TestAuditLogger_ChainIntegrity - TestAuditLogger_VerifyChain - TestAuditLogger_LogFileAccess - TestAuditLogger_Disabled - Tests tamper-evident chain hashing and file access logging
