Detailed Description

The copy loop of the copy fallback: copies a provider stream to a file chunk by chunk and asks CopyBudget before EVERY chunk is written, so a copy never goes over the byte cap or below the free-space reserve.

Plain Java; streams, free space and the stop flag are passed in.

The caller deletes the partial file for every outcome except Outcome#COPIED.
