/**
* Extract nodelist from ZIP archive
*
* This script extracts FidoNet-style nodelist files from ZIP archives.
* It handles nested archives where a ZIP contains .Znn files (which are
* themselves compressed in FidoNet format).
*
* Usage: php extract_nodelist_zip.php <zip_file>
*
* The script outputs the path to the extracted nodelist file to stdout.
* The last line of output MUST be the file path for the update script to use it.
*
* Example (AgoraNet):
* Input: agoranet.zip (outer archive)
* Extract: agoranet.z30 (FidoNet compressed, day 30)
* Output: /path/to/data/nodelists/agoranet.z30
*
* Then import_nodelist.php extracts agoranet.z30 -> agoranet.030 (uncompressed)
