fix(rendering): keep justified bar widths and space bars against one duration reference per layout

perf(rendering): create glyph collections on first use and paint without temporary allocations

perf(rendering): lay out bar headers from shared profiles and build the bounds lookup with fewer allocations

refactor(rendering): decide which bars fit a system before adding them

perf(rendering): reuse systems on resize and cut glyph, beaming and skyline allocations

perf(rendering): hand the bounds lookup from the browser worker as a flat buffer

perf(rendering): paint staff lines once per run of bars

fix(rendering): keep tab note geometry unchanged by painting and generate the midi once per score load

perf(worker): send score and settings to the render worker as plain objects

test(layout-flow): add paint, retained-memory, census and resize probes

perf(rendering): stop retaining painted partials and cut layout, paint and synth allocations

perf(browser): coalesce worker resizes and release the DOM of partials far out of view
