m_checkpoint_manager Module

for restart capabilities.

simulation state to a file. This allows a simulation to be stopped and resumed from the exact state it was in.

Key features include: - Reading all checkpoint settings from a configuration file - Periodically writing the full-resolution simulation state - Handling the full logic for restarting a simulation from a specified checkpoint file. - A safe-write strategy that writes to a temporary file first, then atomically renames it to the final filename to prevent corrupted checkpoints. - Optional cleanup of old checkpoint files to conserve disk space.
