Detailed Description

Boundary condition types, implementations, and handler for the EulerP module.

Provides:

• BCType: Enumeration of supported boundary condition types (Far, Wall, Sym, etc.)
• BCFunc_Impl: Template specializations for each BC type (currently stubs, TODO)
• BC_DeviceView / BC: Device-callable and host-side single BC objects
• BCHandlerDeviceView / BCHandler: Device-callable and host-side BC managers
• BCInput: JSON-deserializable input struct for BC configuration

The BC system uses a runtime switch-dispatch in BC_DeviceView::apply() to route to the appropriate BCFunc_Impl specialization, enabling device-callable BC evaluation on both Host and CUDA backends.
