Pull request overview

This PR aims to speed up SQLite persistence during simulations by tuning SQLite settings and reducing overhead in periodic batch inserts, and it updates the PyPI/TestPyPI publish workflow to handle existing versions more explicitly.

Changes:

• Tune SQLite PRAGMAs for higher sustained write throughput when saveData() is configured.
• Consolidate periodic writes into a single transaction and avoid repeated per-row value recomputation during inserts.
• Update PyPI/TestPyPI publish policy: fail on existing versions for PyPI pushes, and delete/re-publish for TestPyPI PRs; bump patch version.
