Autonomously identified and filled unit test coverage gaps. Added 7 targeted, deterministic tests in __tests__/stunt-double.spec.ts covering mock utilities and edge cases in chat-stream.ts and github-releases.ts. Verified stability with a 10-iteration loop and ensured 100% logic coverage in identified modules. Created .StuntDouble/coverage.md to track improvements.
