Pull request overview
Adds first-class support for the Materialized View application architecture pattern across PatternKit’s runtime, Roslyn generator surface, examples, and documentation—expanding the Pattern Catalog and providing end-to-end tested coverage (runtime + generator + DI + example).
Changes:
- Introduces
IMaterializedView<TState,TEvent>+ fluentMaterializedView<TState,TEvent>runtime with ordered sync/async handlers. - Adds
[GenerateMaterializedView]/[MaterializedViewHandler]attributes and an incremental generator that emits materialized view factory methods plus diagnostics. - Adds a production-shaped order read-model example (fluent + generated), DI integration, documentation, and TinyBDD tests; updates pattern/example catalogs accordingly.

Local validation
