+Extracts every member in a ZIP archive into `destination_directory`.
+
+```uce
+zip_extract("/tmp/example.zip", "/tmp/example-extract");
+```
+
+UCE creates the destination directory and any needed child directories when they do not already exist.
+
+For safety, every member name is normalized and checked before extraction. Absolute paths, drive-qualified paths, empty names, and `..` path segments are rejected so archives cannot write outside the destination directory.
