Detailed Description

Streaming consumer that builds an engine Matrix from the mathicgb-style stream callbacks (idealBegin / appendPolynomialBegin / appendTermBegin / appendExponent / appendTermDone / appendPolynomialDone / idealDone).

Note: AI-generated documentation. Verify against the source before relying on it.

Mirrors the BasicPolyListStreamCollector shape but produces a proper engine Matrix* over a PolyRing instead of a portable BasicPolyList. Used as the bridge between mathicgb's stream input and the engine's typed matrices — value() returns nullptr until idealDone() is called.
