feat: wire protocol integration in TCP server
...
- 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
