c35e7219c8 feat(db-bench): sample — serial modes, histogram stats (T2)
- seed/read/query/write/wal/verify/verify-acked + all (one-process
  campaign: RAM store dies with the process)
- per-op time.ticks, 1us-bucket histogram percentiles (reservoir
  deviation: no element-write/sort in language; better tail anyway)
- Meta expectation rows ride the same WAL verify checks
- finding: hand-built multi<TableClass> SEGVs on drop (elems classed
  OWNED, refs are scalar ids) — worked around, recorded
- finding: reads ~1.6k/s p50 595us vs 287k/s inserts — probe walks
  all slabs; the number 22 exists to surface
