move bench/cross-engine to examples/cross-engine-bench

It's informational/demonstration content (a cross-language comparison
suite), not development tooling, so tools/ was the wrong fit and
examples/ is the right one. bench/ had nothing else in it, so it's
gone. Same directory depth from repo root, so run.sh's ../../ relative
paths are unaffected — verified. Updated its own self-referential
paths (run.sh usage comment, README.md, RESULTS.md) and both links
from the top-level README.
