The worker no longer copies rows when an array cannot grow in place. It
reserves a zeroed region, returns the staged descriptor with a commit
flag, and queues every other request until the main thread (the only
writer) has copied the old bytes and sent commit-rows. Writes that raced
the old worker-side copy were lost; lights in the glTF viewer regularly
ended up at the origin because of it.

Keep hot render state in a generic shared SOA arena and use worker messages only for allocation, graph compilation, loadout changes, and render pacing. Compile external S-expression graphs into upfront WebGPU resources, transient aliases, and reusable render bundles.
