Implemented the "PDF Stamp Operation" feature, allowing users to add text, image, or predefined stamps to PDF documents. - Added `FEATURE_7_PLAN.md` with detailed implementation plan. - Introduced enums (`StampType`, `PredefinedStampType`, `StampPlacement`) in the domain layer. - Added `AddStampAsync` method to `IPdfProcessor` interface. - Implemented `AddStampAsync` in `DevExpressPdfProcessor` using DevExpress API. - Created unit tests for `AddStampAsync` covering various scenarios. - Added `AddStampCommand` in the application layer with validation rules. - Created two new endpoints in `PdfOperationsController` for multipart and Base64 inputs. - Added DTOs for handling endpoint requests. - Wrote integration tests for endpoints to ensure correctness. - Updated `AGENTS.md` and added DevExpress API references. - Documented challenges, considerations, and estimated effort. This commit completes the "PDF Stamp Operation" feature with full test coverage and documentation.
