Adds tests/benchmarks/test_scaling_perf.py with parametrized benchmarks across row-count, column-width, and type-mix axes. Caught the NFETCH-loop bug (Phase 35) immediately on first run. Headline numbers: Bulk insert (executemany in transaction): 1k rows: 23 ms (23 us/row) 10k rows: 161 ms (16 us/row) 100k rows: 1487 ms (15 us/row, ~67k rows/sec sustained) SELECT (linear scaling, near-constant per-row): 1k rows: 2.7 ms (2.7 us/row) 10k rows: 25.8 ms (2.6 us/row) 100k rows: 271 ms (2.7 us/row) Wide-row SELECT (1k rows x N cols): 5 cols: 2.4 ms 20 cols: 5.1 ms 50 cols: 10.1 ms Type-mix SELECT (INT + VARCHAR + DECIMAL + DATE + FLOAT + SMALLINT): 1000 rows: 4.7 ms (4.7 us/row, ~1.7x baseline) Per-row codec cost is essentially constant from 1k to 100k rows (2.7 us/row), proving parse_tuple_payload optimizations (Phases 23-25) hold at 100x scale with no GC-pause amplification or memory-pressure degradation. Per-row insert cost actually DECREASES with scale (23us at 1k to 15us at 100k) - Phase 33's pipelining amortizes prepare/release overhead better at larger N. 10 new parametrized benchmarks. Total: 77 unit + 249 integration + 43 benchmark = 369 tests.
