chore(publish): Keep the mlucas binaries out of git and the bundle

src/Script_ABC_Blanton/hammer/ is ~99 MB of unstripped mlucas ELF
binaries (avx512 / avx2 / avx / sse2 / generic-c). They come with the DUT
image, so this repo has no reason to carry them - and a binary tree that
size is permanent once committed: every clone pays for it forever.

publish.sh excluded them too, because rsync copies whatever happens to be
sitting in src/. Without the exclude the delivery bundle was ~100 MB from
a machine that had the binaries and ~200 KB from a fresh clone.

While there, usage() read a fixed line range of the header, so adding a
Version History entry pushed code into the usage text. It now reads up to
the first line of code.
