docs(web): add Dream Progress screenshots + capture script

Wires up the DEV-only /dream-progress showcase to a Playwright script
that captures idle/active/stalled variants for documentation. Also
regenerates routeTree.gen.ts to include the new queue + showcase routes
and folds in Biome formatter fixes.

Run `node scripts/screenshot-dream-progress.mjs` from packages/web with
the dev server up to refresh the images.
