Cluster HA Orderbook

Claim-based Cluster publishing with an HA-shaped limit order book. Proves try_claim patterns and never-stale book snapshots under leader transitions.

• Offline pipeline (ha_offline_pipeline) — claim + encode + verify without a live cluster.
• Kill-leader test (ha_kill_leader) — validates book integrity across leader changes (requires Java harness).
