Chaos harness enhancements: - transport_mix config: weighted random transport assignment for random topologies (erdos_renyi, random_geometric) with UDP/Ethernet/TCP - Replace LoRa with Bluetooth L2CAP in cost-based/mixed-tech scenarios using realistic netem values (15-40ms delay, 5-15ms jitter, 2-8% loss) - New churn-20-mixed scenario: 20-node Erdos-Renyi with 60% UDP, 20% Ethernet, 20% TCP, full netem/link-flap/churn/bandwidth config - Expanded chaos README with full scenario catalog in four categories Static harness: - Updated README with topology table and scenario count

# Test subjects:
|
|
# - n06 has fiber (n03) and Bluetooth (n02) parents — should pick n03
|

# - n08 has fiber (n03) and Bluetooth (n04) parents — should pick n03

# Netem mutation shifts fiber-only links between normal and degraded.
