Generate the Payload importMap at build time (Dockerfile) and dev time
(predev hook) with dummy S3_* envs, eliminating the class of bugs where
the admin goes blank because the S3ClientUploadHandler entry is missing
(OPS69/OPS72/OPS73).
Changes:
- Dockerfile: add pnpm generate:importmap with dummy S3_* envs before next build
- scripts/predev-importmap.mjs: predev hook that generates importMap if missing or stale
- Delete scripts/check-importmap-s3.mjs (guard no longer needed)
- Delete tests/unit/importMapS3UploadHandler.unit.spec.ts (unit pin no longer needed)
- Remove check-importmap-s3.mjs step from CI workflows
- Add importMap.js to .gitignore (build artifact, not committed)
- Update AGENTS.md with new contract
Closes#928
