fix(bench): Reduce primitives benchmark to prevent browser tab crash during bench:save

Trim to 5 representative primitives (rect, circle, group, text, path) and cap scaling at 250 instances. The full suite with 7 primitives and 1000-instance scaling accumulated enough memory to crash the browser tab when run alongside all other benchmark suites.
