build-and-push failed on the last deploy: chromium-headless-shell's single ~181MB binary can't be split across Docker layers the way this project's pip/npm installs were (those are many independently- installable smaller packages; this is one file), and confirmed-failed to push past the registry's per-layer size limit. Moves the `playwright install chromium-headless-shell` step from the Dockerfile to start.sh, caching into PLAYWRIGHT_BROWSERS_PATH on the /data volume -- only the very first boot on a fresh volume downloads it, every boot after that is a no-op check. The image itself no longer grows by ~262MB, so nothing new gets pushed to the registry at all.
