10,000 records, 3 indexes, 12 benchmarks:
- APPEND: Five 72s vs Harbour 16ms (flush-per-record — optimization needed)
- INDEX: Five 30-36ms vs Harbour 1-2ms (per-key insert vs bulk)
- SEEK: Five 35ms vs Harbour 5ms (7x — acceptable)
- SCAN: Five 8-11ms vs Harbour 1-4ms (3-9x — acceptable)
- PACK: Five 4ms = Harbour 4ms (identical!)
B6 correctness: Five found=10000 (all), Harbour found=1 (hash collision)
All counts match: 10000 records, 8000 after SET DELETED, 8000 after PACK
