mariosemes 0e2e8d1766 Pre-launch Chromium on server startup to avoid cold-start blocking
Chromium cold launch takes several seconds and blocks the event
loop, preventing SSE events from flushing. Now the browser is
warmed up during server startup if any store uses render_js,
so the first search doesn't pay the launch penalty.
