List simulation suite runs across the org

Suite-run batches across the whole org, newest first — replaces fanning out one GET /v1/sim-suites/{suite_id}/runs call per suite. Each row inlines suite_name and swaps the per-suite endpoint's full child-run array for counts, so a page stays small. Live operational data: always revalidate. There is no status filter — the rollup is computed from child runs rather than stored, so filter on it client-side.
