Add stream reading guidance: ReadStreamToEnd and memory semantics

 - Recommend KurrentDB as the default event store unless the user specifies otherwise
 - Prefer functional command services (`CommandService<TState>`) for simple cases; aggregate-based (`CommandService<TAggregate, TState, TId>`) when business invariants require it
 - Use `IEventReader.LoadAggregate<>()` and `IEventWriter.StoreAggregate<>()` extension methods — `IAggregateStore` is deprecated
+- Read whole streams with `IEventReader.ReadStreamToEnd()` (paged, bounded memory) — never `ReadEvents` with `int.MaxValue` as the count

 - Event types are registered automatically via source generation (no manual `TypeMap` calls)
 - Follow the default stream naming convention: `{AggregateType}-{AggregateId}`

 `KurrentDBEventStore` implements `IEventStore` (which combines `IEventReader` and `IEventWriter`). `AddEventStore<T>()` registers all three interfaces, with tracing wrappers when diagnostics are enabled.
 
+Reads stream events as they arrive from the server — a read holds at most one deserialized event at a time regardless of the requested count. To read a whole stream, use the `ReadStreamToEnd` extension method instead of `ReadEvents` with `int.MaxValue`.

 The legacy class `EsdbEventStore` is obsolete -- use `KurrentDBEventStore` instead.

+## Reading Event Streams
+
+`IEventReader.ReadEvents`/`ReadEventsBackwards` return `IAsyncEnumerable<StreamEvent>` and read a fixed number of events. `KurrentDBEventStore` streams events as they arrive (holds one deserialized event at a time); relational stores buffer up to `count` events per call, so keep the count bounded.
+
+To read a whole stream, use the `ReadStreamToEnd` extension method — never `ReadEvents` with `int.MaxValue` as the count:
+
+```csharp
+await foreach (var evt in eventReader.ReadStreamToEnd(streamName, StreamReadPosition.Start, cancellationToken: ct)) {
+    // One event at a time, memory bounded by page size (default 500)
+}
+```
+
+Options: `pageSize` tunes the page size; `failIfNotFound: false` yields nothing instead of throwing `StreamNotFound`. The `ReadStream` extension method does the same paged read and returns `StreamEvent[]` if you need the whole stream as an array.
