Deterministic CPU multithreading: supernodal Cholesky, parallel elements, LBM blocks (#50)
* parallel: deterministic thread pool helpers for the solvers (fixed partitions, ordered results)
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm
* solver: supernodal left-looking Cholesky, multithreaded with a fixed operation order

* solver: parallel element matrices, stresses, Lanczos block solves and products (sums in the sequential order)

* explicit: element updates in parallel, nodal forces added in element order (bit-identical to the sequential loop)

* lbm: collision and streaming by fixed cell blocks in parallel, wall forces in link order (bit-identical)

* engine: threads setting for the solve commands (session default from MODELCRAFT_THREADS or the cores); bit-identity test on 1, 2 and 7 threads
