database/sql-backed MySQL client with launcher lifecycle, health check, unit-of-work via context injection, and structured error mapping. What's included: - Executor / Tx / Client / Component interfaces using database/sql native types (sql.Result, *sql.Rows, *sql.Row) - Tx.Commit() / Tx.Rollback() without ctx, matching the honest database/sql contract - New(logger, cfg) constructor; *sql.DB opened in OnInit - Config struct with env-tag support for all pool tuning parameters - UnitOfWork via context injection; GetExecutor(ctx) returns active *sql.Tx or *sql.DB - HandleError mapping MySQLError.Number to xerrors codes (1062 → AlreadyExists, 1216/1217/1451/1452 → InvalidInput, ErrNoRows → NotFound) - Driver imported as mysqldrv alias to avoid package name collision - health.Checkable at LevelCritical; HealthCheck delegates to db.PingContext Tested-via: todo-api POC integration Reviewed-against: docs/adr/
