Phase 6 of the Interactivity-First Refactor. Strip decorative async throughout the FEM algebra and engine, implement a staged InteractiveJob graph from validation through meshing, assembly, iterative/direct/eigen solving and finalize, with persistent bounded state, progress, cancellation, checkpointing, deterministic reductions, and visual preview data. Make meshing coarse-first and incrementally refined; implement persistent PCG/LDLT/subspace iteration jobs; verify reference tolerances, coarse preview under 50 ms, stale-edit cancellation, and no step at or above 8 ms.
