Pull request overview

This PR extends the PyAnsys Geometry client to model Datum Points as first-class design entities (including import from existing designs), integrates them into Named Selections, and adds missing delete/search APIs for several non-body entities via new/updated gRPC service endpoints.

Changes:

• Introduces DatumPoint client type, server (de)serialization, and component/design APIs for creating, deleting, and searching datum points.
• Extends NamedSelection and supporting helpers/gRPC to include datum points as selectable members.
• Adds delete/search support for coordinate systems and design curves, with new integration tests covering the added behaviors.

• The members parameter docstring line is > line-length limits, and # Noqa: E501 is ineffective here (and wrong-cased for standard # noqa). This is likely to fail linting; wrap the docstring text instead and drop the noqa.

My only question is - does create_design_points need to stay for a while and be marked as obsolete, or is it okay to make breaking changes by removing it now

[jacobrkerstetter]

@jonahrb The _grpc layer is ok because I swapped everywhere that it is used to appropriately use create_datum_points and create_design_points. The user should never feel this change because they should never call the _grpc layer directly.
