Module congestion_controller 

TCP-inspired multi-algorithm congestion controller for IPFRS peer data streams.

Implements SlowStart, CongestionAvoidance, FastRecovery, and Idle phases with five distinct algorithms: Reno, Cubic, BBR, Vegas, and Westwood.

Legacy API

The original per-peer PeerCongestionController and MultiPeerCongestionManager are retained for backwards compatibility.

New API

Use CongestionController for full multi-algorithm support.
