Function run_clone_summary
pub fn run_clone_summary(db: &FactsDb) -> Result<Vec<CloneSummary>>Expand description
Per-file clone-group counts from the clones table. Empty result
when no clone groups exist (small repo, no Tier-1 sources, or
min_clone_node_count filtered everything out at ingest time).
One row per path that appears in ≥ 1 clone family — files with
zero clone groups are dropped so the payload stays compact.
§Errors
