Add scripts/docker-prune.sh (build cache >72h capped at 4g, unreferenced images >7d, stopped containers >24h; never volumes), run it after every CI deploy and compose update, and schedule a nightly prune from the host-side jobs-worker. Tighten the deployment contract tests to assert the scoped-prune boundaries.
Drop the leftover Playwright browser install and e2e smoke test from the deployment script, and update the deployment contract tests to cover the verify-deployed-release smoke check instead.
- Move the pnpm store, apk and .next caches into --mount=type=cache so
dependencies are shared across builds instead of duplicated in fresh
image layers (was the source of unbounded disk growth).
- Replace the deprecated --keep-storage prune flag in ci-deploy.sh with
the working --max-used-space=4g (buildx v0.37 renamed the flag). The
deprecated flag silently did nothing, so the BuildKit cache kept
growing unbounded (was 15.86GB); it is now capped at 4GB after every
deploy.
next.config.ts falls back to `git rev-parse HEAD`, but the build context has
no .git (excluded by .dockerignore), so every CI build printed fatal git
errors and stamped the release as "unknown". Pass the deploy commit sha as a
NEXT_DEPLOYMENT_ID build-arg so git is never invoked and the actual commit
reaches NEXT_PUBLIC_CMS_RELEASE and deploymentId.
