pombast CI: fix publish, add log artifacts

publish.sh checked `git diff --quiet` after staging the files with
`git add`, so it always saw a clean working tree and reported "No
changes" -- nothing was ever committed to status.scijava.org's gh-pages
branch. Check staged changes with `git diff --cached --quiet` instead.

Also upload target/pombast logs (mega-melt validation + per-component
build logs) and the generated reports as workflow artifacts, so melt and
smelt failures can be diagnosed without waiting on a Pages deploy, and
set COLUMNS so the Rich tables in the CI logs are legible.
