Subject: [PATCH 1/2] Drop the wall-clock limit from the bytes round-trip test

The test failed whenever its body took over 2s, which a shared CI runner does now and then, while the round trip itself passed. It was left in to debug #1194; the test now checks only what it reads back.

Subject: [PATCH 2/2] Retry the TileDB release list download, and fail plainly
 if it can't be fetched

file(DOWNLOAD) without STATUS leaves an empty file on failure and no error, so a dropped download surfaced later as "string sub-command STRIP requires two arguments". It is now retried three times and then reported with the URL and reason.
