CodeClone b5: structural review that finally knows what your tests cover

In earlier posts, I wrote about why I built CodeClone, why I exposed it through MCP for AI agents, and how b4 turned it into a real review surface for VS Code, Claude Desktop, and Codex. b5 is the release where structural review stops being a parallel universe to your test suite. Until now, CodeClone could tell you that a function is long, complex, duplicated, or coupled to everything - but it had no idea whether that function was covered by a single unit test. That mattered than I wanted to admit.
