CI: let the PR checks fail, check the built manifests, drop the auto bots

- continue-on-error came with the upstream template: lint, build and test
  have been red here while every pull request read as passing (12 test
  failures and 603 lint errors before this branch). fail-fast: false keeps
  each step running when another fails.
- after build, scripts/check-built-manifests.py checks the package.json in
  every build/ directory, the file npm receives (the January 2026 ./cjs/cjs
  fault, and the wasm 7.5.19 one).
- auto-approve/auto-merge (upstream author's actions, merge on a '-auto'
  label once checks reported) are removed, as in pezkuwi-apps.
