Performance

Generated by pnpm bench --write and pnpm acceptance; the targets and the reference machine are in decision 0032 and quality.md. Each case runs after a few unmeasured runs; the editor’s path is the analysis a file gets after an edit (compile, layout and diagnostics inside its project) and a canvas drag from the message to the new drawing.
