el-install.el explicitly imported runtime/*.el modules (string, env, fs, exec,
json, http), which elb compiled to .c files in the shared dist/bin out_dir.
Linking those alongside el_runtime.c caused multiple definition errors for
every runtime function (http_get, http_patch, etc.). The runtime .el files are
thin wrappers over seed primitives already compiled into el_runtime.c — no
import needed.
Fixes:
- Remove all explicit runtime imports from el-install.el (root cause)
- Add --clean to every elb invocation in sdk-release.yaml so each build
starts with a clean out_dir (defense-in-depth against stale .c files)
- Add elb build + epm/el-install build steps to ci-dev.yaml and ci-stage.yaml
so linker errors are caught on every PR, not just stage->main
