test(kuna): preserve caller and producer graph failure context

Align malformed call-graph retry assertions with caller-attributed errors while retaining the parser operation in diagnostics and the cause. Keep all malformed shapes, corrected-response retry, exact native-command count and owned-client cleanup coverage.

Validation: clean main reproduces 3 failed / 14 passed; corrected complete Kuna boundary selection passes 266 tests across 26 files; full check:ci and complete current-head CI passed. Greptile 5/5; human owner reviewed the diff/evidence and explicitly declared readiness. Codex review remains unavailable due repository usage limits. Test-only; no production/schema/authority change or real-engine qualification.

Fixes #4701.
