depend-cleanup.sh: Add commented example and remove one more entry

Although the epoch is 20250805, the push for that wasn't until 20250814,
so we can remove the 20250813 entry for tcopy, per jrtc27. Also, include
an example of changing a shell script to a binary, since that's
deceptively tricky, though the code looks simple, per emaste.

There should be no functional changes here.
