patch

GitHub tracking-issue creation now searches the target repo (open and closed issues) for likely duplicates before opening a new issue, keyed on the task's File Scope paths and symptom keywords. Matches link the existing issue to the Fusion task. Opt out with project setting githubTrackingDedupEnabled: false.
