The probe compared each candidate request size against a "known-good" download
that used micromate's DEFAULT chunk size -- which is now 16,384. That makes the
experiment circular: if 16 KB is broken on a given link, the reference is broken
the same way and every comparison passes.
The control is now pinned to THOR_CHUNK_SIZE. 1024 is the size with THOR's own
captures behind it and the only one proven over a cellular modem, so it is the
thing to measure against.
Also raised the default idle gap from 2 s to 3 s. A 16 KB response is ~1.4 s of
serial time at 115200 before the modem's ~1 s forwarding delay, and too small a
gap makes a slow link look like a clamp -- which would read as a device limit
that is really a timeout.
