neato plain/plain-ext parity dashboard
Differential survey of @knowvah/dot-engine neato plain/plain-ext output vs the native dot -K neato oracle (test/corpus/plain-walk.ts), semantic comparison per docs/conformance.md (±0.01 deterministic tolerance, ±0.5 for the iterative engines). Regenerate: npx tsx test/corpus/plain-walk.ts neato && npx tsx test/corpus/parity-report.ts.
