fileZipDir

Creates a ZIP archive containing all files and subdirectories from the source directory. Recursively traverses the directory tree and adds all contents to the archive using MZ_DEFAULT_COMPRESSION. Returns 1 on success, 0 on failure (NULL parameters or ZIP creation error).

Uses miniz library (mz_zip_writer) and AddDirToZip helper function for recursion. Preserves directory structure within the ZIP. All files and subdirectories are compressed. Useful for archiving project folders or creating backups.
