feat: auto-rebalance, Cypher-like graph queries, tutorial examples — 232 tests
Cluster Auto-Rebalance:
- ClusterMembership with onNodeJoin/onNodeLeave/onNodeFail
- Automatic shard reassignment on node failure
- Rebalance triggers on member changes
Cypher-like Graph Queries:
- MATCH/CREATE/MERGE/DELETE query parser
- Full pattern parsing: nodes with labels/properties, edges with labels
- WHERE, RETURN, ORDER BY, LIMIT clauses
- executeCypher for basic graph matching
Tutorial:
- 8 comprehensive examples: KV store, B-Tree, vector search, graph, FTS, MVCC, BaraQL parsing, community detection
- Runnable demo with all major engines
