Top-10 holdings churn between two snapshot dates

Diff between the top-10 holdings of two ETF snapshots. Returns three buckets: new_top_10 (appeared in to_date, absent from from_date), dropped_from_top_10 (in from_date, absent from to_date), and weight_changed (present in both). The mandatory caveat field discloses that the upstream feed reports a top-10 sample only - drop-outs may remain in the portfolio but fell below the top-10 rank threshold.
