Add dev/stage CI pipelines and expand sdk-release to full prod pipeline

- Add ci-dev.yaml: builds elc gen2→gen3, runs 4 test suites, publishes
  el/elc + el_runtime.c + el_runtime.h to foundation-dev Artifact Registry
- Add ci-stage.yaml: same as dev but targets foundation-stage registry
- Update sdk-release.yaml: publish 3 SDK artifacts to foundation-prod
  Artifact Registry after Gitea release; expand dispatch list from 2 to 6
  downstream repos (el-ui, elp, elql, el-ide added alongside engram/forge)
