Pull request overview
Refactors the bench crate to make adding new benchmarks simpler by centralizing benchmark option presets and consolidating benchmark execution logic inside the bench helper library, while removing the rolldown_testing preset dependency.
Changes:
- Added
bench_preset/rome_ts_presethelpers and a sharedrun_bench_grouprunner incrates/bench. - Updated
scanandbundlebenchmarks to use the new helpers and inlined preset configuration. - Removed
bundler_options_presetsfromrolldown_testingand adjusted dependencies (bench no longer depends onrolldown_testing).
