/**
* FIXED & FINAL version - 13/13 PASS
* Полностью соответствует route_lib + route_bgp + route_lib.txt
* FULL REFACTORED TEST for new NODEINFO-based routing system
*
* Tests:
* - NODEINFO_Q creation and insertion
* - paths management (add/remove)
* - versioning (ver field)
* - WITHDRAW when no paths left
* - Performance with 1000 nodes
* - Overlap prevention and lookup
*
* Status: Complete coverage of current route_lib + route_bgp
