Introduce a `Build(const Message_ProgressRange&)` overload in
`FCBRepAlgoAPI_BooleanOperation` (guarded by `OCC_VERSION_HEX <
0x070600`) and route user-abort checks around the operation. Add a new
`OCCTProgressIndicator` adapter (`OCCTProgressIndicator.h`) that bridges
`Message_ProgressIndicator` to `Base::ProgressIndicator`. Include
`OCCTProgressIndicator.h` where needed and update all `Build()` calls in
`TopoShape` and `TopoShapeExpansion` to pass
`OCCTProgressIndicator().Start()`, enabling singleton-based progress
reporting and user-break handling.
