When choosing which duplicate to keep, the merge target now considers
both dependentCount (children/blocked-by) AND dependsOnCount (dependencies).
This ensures issues with ANY structural connections are preferred over
empty shells, rather than only considering children.
- Updated chooseMergeTarget to calculate weight = dependentCount + dependsOnCount
- Updated display output to show weight instead of just dependents
- Updated JSON output to include dependencies and weight fields
- Added tests for dependsOnCount inclusion and combined weight calculation
