feat: subnet-level attack detection (prefix_stats) 
- XDP: prefix_stats LRU map, per-/24 (v4) and /64 (v6) SYN/packet counters,
  incremented post-blacklist/throttle (xdp/core/prefix_stats.h)
- userspace: SubnetDetector escalation ladder Monitor->StrictLimit->Challenge->Block
  with spoof-gate (Block requires >= min_unique_sources, CGNAT-safe)
- config: [detect.prefix] section (enabled=false by default)
- fallback without XDP: engine SubnetTracker aggregates connections per-prefix
- fix: PrefixStatsVal::from_bytes for xdp feature build; prefix_len 24 vs 64
