Pull request overview
Adds a new Domain Modeling “slice” for the DDD Bounded Context pattern, spanning runtime APIs, a source generator, an importable DI example, tests, docs, and benchmark coverage to meet the production-readiness catalog requirements tied to #403.
Changes:
- Introduces
BoundedContextDescriptorruntime API (capabilities + adapters) plus fluent builder validation/ordering. - Adds
BoundedContextDescriptorGenerator+ abstractions attributes + Roslyn tests/diagnostics entries. - Integrates a Fulfillment bounded-context example into DI, catalog coverage, docs, and BenchmarkDotNet scenario/docs count updates.
