Detailed Description

Phase 17 showcase: compression, async writer and delta snapshots for ca-checkpoint.H.

Three independent demos (selectable via the first CLI argument):

• compress — saves the same engine state both raw and DEFLATE-compressed; reports the on-disk size and the compression ratio.
• async — measures the per-step wall time of a long run with and without an Async_Checkpoint_Writer plumbed into a Periodic_Checkpoint_Observer, and prints the relative overhead.
• delta — captures a baseline snapshot, advances the engine, stores a save_delta_checkpoint, reloads the baseline into a fresh engine and applies the delta on top. Verifies cell-by-cell that the reconstructed state matches the live engine.
• all — runs all three back-to-back (default).

Run: ./ca_checkpoint_phase17_example [mode] [side] [steps]

Defaults: mode=all, side=128, steps=200.
