chain-v0.2.2-alpha: Hydra-routed block propagation

What's new

• Hydra-routed block propagation — finalized blocks delivered through stake-secured routing network (delivery rights, Ed25519 receipts, capacity-weighted tree decomposition) instead of gossip broadcast
• P2P sync fix — non-mining fullnodes can now receive and sync blocks from miners
• Bundled shared libraries — libhpn_operator.so + proof verification libs included in .tar.gz

Breaking

Nodes running chain-v0.2.1-alpha will auto-update to this version within 30 minutes.
