Multi-Stream Projections in Marten

Multi-stream projections in Marten: identity routing, fan-out patterns (one event updates many documents), custom groupers with DB lookups, and ViewProjection.

Use when a read model aggregates events across streams, segments a stream by time window, or needs composite identity keys.
