The solver.py refactoring renamed most solver classes from *Solver to
*Model (e.g. DistributedSolver → DistributedModel). The docs still
referenced the old names, causing the Quarto site build to fail with:
ImportError: cannot import name 'DistributedSolver' from 'mlsysim'
- Fix executable code cells in tutorials/distributed.qmd
- Update non-executable code examples across 10 doc files
- Rename 19 API reference files from *Solver.qmd to *Model.qmd
- SensitivitySolver and SynthesisSolver retain their names (correct)
