Add stemedb-cluster crate implementing horizontal scaling: - SWIM-based membership protocol for node discovery and failure detection - Consistent hashing (jump hash) for subject-to-shard routing - Range management with dynamic split (>64MB) and merge (<20MB) operations - Stateless HTTP gateway for client request routing via axum - Meta-range gossip merge for cluster-wide metadata propagation Includes restrictive CORS policy, proper error propagation from routing, replica cache invalidation on node failure, and 84 tests (57 unit + 27 integration). Raft MV coordination deferred per design decision. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
