refactor(docker): split browser image into per-core prebuilt variants

Replace the single browser image (which required local build) with three
prebuilt images: browser-chromium, browser-firefox, and browser (both).
Each is exposed as a separate Docker Compose profile so users can simply
`docker compose --profile browser-chromium up -d` without any local build
step, significantly reducing install time.
