fix: distributed transaction and sharding bugs
...
- disttxn: rollback now correctly updates participant state (was modifying a copy)
- disttxn: bare except replaced with CatchableError
- sharding: migrateData condition was always false, now correctly migrates data
- sharding: unsafe cast[string] replaced with manual byte-to-char conversion
- sharding: bare except replaced with CatchableError
- server: parseUInt replaced with parseBiggestUint for uint64 portability

fix(distributed): 2PC atomicity, DISTTXN handler, sharding bugs, gossip timers
...
- disttxn: prepare failure rolls back already-prepared participants (C1)
- disttxn: commit failure rolls back committed participants (C2)
- server: DISTTXN handler uses real DistTxnManager (C3)
- server: DistTxnManager initialized in newServer() (H1)
- sharding: getShardRange returns -1 instead of 0 for out-of-range keys (M6)
- sharding: binary search in consistent hashing ring (M7)
- gossip: startHealthCheck() and startGossipRound() async loops
- 283 tests, 0 failures

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
10 new tests (232 total, all passing)

feat: full BaraQL (GROUP BY/JOIN/CTE/aggregates), Raft consensus, sharding — 107 tests
...
BaraQL parser extended:
- GROUP BY + HAVING clauses
- JOIN (INNER, LEFT, RIGHT, FULL, CROSS) with ON conditions
- CTE (WITH ... AS) with multiple CTEs
- Aggregate functions (count, sum, avg, min, max)
- CASE/WHEN/THEN/ELSE/END expressions
- BETWEEN, IN, LIKE/ILIKE, IS NULL/IS NOT NULL
- Dotted path identifiers (table.column)
- Subqueries in FROM clause
- CREATE TYPE with colon syntax (name: type)
- UPDATE SET ... WHERE, DELETE FROM ... WHERE
Infrastructure:
- Raft consensus: leader election, log replication, RequestVote/AppendEntries
- Sharding: hash-based, range-based, consistent hashing, rebalancing
- Fixed lexer: = is equality, := is assignment, added : (colon) token
- 34 new parser tests (107 total, all passing)
