ci: rebuild ci-base on SDK release; publish elb + el_runtime.js to Artifact Registry

- sdk-release.yaml: add elb and el_runtime.js to foundation-prod uploads
- sdk-release.yaml: add 'Rebuild ci-base' step — patches ci-base:latest with
  freshly built El SDK after each main branch release (pull → overlay → push)
- sdk-release.yaml: add neuron-web to el-sdk-updated dispatch so downstream
  CI rebuilds automatically on SDK update
- ci-dev.yaml: add elb build step and publish elb + el_runtime.js to
  foundation-dev alongside elc and runtime
