fix: PR CI works without secrets — use committed El runtime for pull_request builds

Gitea does not inject secrets for pull_request events. All push/workflow_dispatch
CI was already working. PR builds were failing at Clone el and Authenticate to GCP.

Fix: for pull_request events, skip El clone and GCP auth entirely. Instead build
EL_HOME from committed files: bin/elc-linux-amd64 + runtime/{el_runtime.c,.h,.js}.
build-stage.sh already knows about bin/elc-linux-amd64 for JS compilation; this
extends that pattern to the native compiler and JS runtime.

Docker --cache-from is skipped implicitly (no docker auth configured for PR builds)
— BuildKit handles unauthenticated cache-from gracefully, continuing without cache.
