- Upgrade Criterion 0.5 → 0.8.2 - Split 4 broad bench files into 14 focused targets - Add Rust runner binary with per-target start/done logging - Add wrap_render benchmarks (all 4 WrapMode variants × 2 sizes) - Add undo_redo benchmarks (undo/redo × 3 history depths) - Apply benchmark_group + SamplingMode::Flat + reduced sample_size on slow insert cases to cut total run time from ~28 min to ~12 min - Rewrite bench/README.md to document runner, targets, and workflow
