This PR prevents Zip Slip / Path Traversal issues during ZIP and JAR archive extraction by validating archive entry paths before writing files to disk. Entries that would resolve outside the intended extraction directory are rejected, ensuring extraction remains confined to the target location.
In addition to the implementation changes, regression tests have been added to verify that malicious archives containing traversal entries (for example,
../../evil.txt) are rejected and cause extraction to fail safely.
