scripts/assert-deploy.ts polls /api/version on prod + demo and asserts the
served data.version matches an expected value, printing each target's
buildSha and exiting non-zero on a mismatch or after a bounded retry loop.
This catches the BuildKit layer-cache pitfall where the deploy reports
clean but /api/version still answers the prior release. Run via
`pnpm dlx tsx scripts/assert-deploy.ts <version>` — not bundled into the
standalone image. Document it in the deploy runbook.
