Fixed the `scc`/`jscpd`/`sem` corroborating signals to analyze a change's full implementation window instead of only its final archiving commit. Previously, workflows with several commits between implementing and archiving a change would only ever see whatever the archiving commit itself touched — often just a folder move with no code in it.
Verified against a real project's archive history, not just synthetic tests: 8 of 15 changes now correctly widen (one from 14 files to 47).
See CHANGELOG.md for the full history.
