:content
Extracts every member in a ZIP archive into `destination_directory`.


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.

:example
DValue entries;
entries["note.txt"] = "extracted content";
zip_create("/tmp/doc-zipext.zip", entries);
mkdir("/tmp/doc-zipext-out");
zip_extract("/tmp/doc-zipext.zip", "/tmp/doc-zipext-out");
print(file_get_contents("/tmp/doc-zipext-out/note.txt"), "\n");
dir_remove("/tmp/doc-zipext-out", true);
