- Added TxnManager to server and ExecutionContext
- Per-connection ExecutionContext with isolated transaction state
- BEGIN creates new transaction via MVCC
- INSERT/DELETE uses transaction write buffer when active
- COMMIT flushes write set to LSM-Tree
- ROLLBACK aborts and discards pending writes
- cloneForConnection() shares tables/btrees/data, isolates transactions
- All 216 tests pass
- Server now reads binary wire protocol messages (header + payload)
- Implements recvExact for reliable message framing
- Query execution against LSM-Tree for SELECT/INSERT/DELETE
- SELECT supports point reads (WHERE key = 'value') and full scans
- INSERT parses simple EdgeDB-style syntax
- DELETE with WHERE clause
- Wire protocol responses: Data, Complete, Error, Pong
- Export wire protocol read/write helpers for external use
- Add scanMemTable to LSMTree for full scans
- Add GEL/ to .gitignore
- All 214 tests pass
