Solution C - Hybrid temp-file streaming: - ZipPort trait now returns NamedTempFile instead of Vec<u8> - ZipService writes to a temp file via ZipWriter<std::fs::File> (O(1) RAM) - Files are read in 64KB stream chunks via get_file_stream() instead of get_file_content() - HTTP response streams the temp file via ReaderStream (never loads full ZIP in memory) - Temp file auto-deleted on drop after response completes - Removed dead imports (HeaderName, HeaderValue, Cursor, Read)
