 ### Added
 
 - **QEC Stim MPP Import**: Added utilities for building `StabilizerCode` inputs from unsigned Stim `MPP` layers, including sparse Stim qubit id mapping, coordinate import, multi-layer selection, detector/logical-observable import, and the optional `graphqomb[stim]` extra. Signed products using inverted Pauli targets are rejected because stabilizer signs are not retained.
