Module peer_selector 

Adaptive peer selection based on Freenet patterns

Implements sophisticated peer selection that favors reliable, fast peers:

• Per-peer performance tracking (RTT, success rate)
• RFC 2988-style smoothed RTT calculation
• Exponential backoff for failing/slow peers
• Fairness constraints to prevent overloading any single peer
• Weighted selection combining multiple signals
