artdag: optimize composition pass (fuse + dce) + 4 tests
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 1m4s

artdag/optimize entries outputs fusible? fuses the entry list then DCEs against
the output names — sinks survive fusion (never absorbed), so output-equivalent
with fewer nodes. optimize 22/22, total 132/132.
