Detailed Description

Turn a `run_channel_18.py` CHECKPOINT into the profiles NPZ, without waiting for a chunk to end.

The running sums live in the checkpoint (`acc_*`), so the campaign can be read at any moment —
which is the point: `stats.npz` is only written when a chunk finishes, and a chunk is hours.

  python profiles_from_ckpt.py runs/prod/ckpt.npz [--out stats_now.npz]

It reuses `run_channel_18.py`'s own `profiles()` so there is one definition of what the profiles
are; that import needs `peclet.flow` on the path (any build — the transformation touches no solver
state).
