feat(db-postgres): initial implementation — pgx pool with lifecycle and UnitOfWork (v1.0.0) Introduces code.nochebuena.dev/einherjar/db-postgres — the PostgreSQL database starter for the Einherjar framework. Absorbs the postgres package from micro-lib, replacing fmt.Errorf wrapping with core/xerrors and migrating from pgx v4 to pgx v5. Interfaces (CT-6: one TypeSpec per file): - Executor — Exec, Query, QueryRow (pgx-native types) - Tx — Executor + Commit(ctx), Rollback(ctx) - Provider — GetExecutor, Begin, BeginTx, Ping, HandleError - Component — lifecycle.Component + observability.Checkable + Provider + Stats() - UnitOfWork — Do(ctx, fn) Implementation: - New(logger, cfg) Component — pool not created until OnInit - OnInit: pgxpool.NewWithConfig with duration parsing; 30s timeout - OnStart: PING with 5s timeout; logs "postgres: connected" - OnStop: pool.Close(); logs "postgres: closing pool" - GetExecutor: returns active Tx from context (ctxTxKey) or pool; nil-safe - Begin/BeginTx: wraps pgx.TxOptions; wrapped in xerrors on error - HealthCheck: delegates to Ping; Priority LevelCritical - Stats() *pgxpool.Stat — zero value when pool uninitialized - NewUnitOfWork(logger, provider) UnitOfWork — Begin+inject+commit/rollback - HandleError: UniqueViolation→ErrAlreadyExists, ForeignKey/Check→ErrInvalidInput, pgx.ErrNoRows→ErrNotFound, all others→ErrInternal Config (EINHERJAR_PG_* env vars): Host, Port(5432), User, Password, Name, SSLMode(disable), Timezone(UTC), MaxConns(5), MinConns(2), MaxConnLifetime(1h), MaxConnIdleTime(30m), HealthCheckPeriod(1m) - Component interface embeds observability.Identifiable; identifiable.go implements ModulePath and ModuleVersion via runtime/debug.ReadBuildInfo() — prints in launcher banner
