Returns share-buyback / stock-repurchase activity in one of two modes:
- CROSS-MARKET (no ticker): latest reported buybacks across all companies,
sorted by dollar amount spent (largest first). Use for 'biggest buybacks',
'top repurchase companies'. A single company may appear multiple times for
different fiscal quarters.
- PER-TICKER (ticker provided): historical quarterly buyback series for one
ticker. Use for 'AAPL buyback history', 'MSFT repurchase trend'.

If empty, returns the cross-market list.
limit: Cross-market mode only — max rows (default: 25, max: 100).

Returns:
Cross-market mode: { totalCount, data: [{ ticker, companyName,
