CI pipeline: replace separate FE + BE image builds with single unified Dockerfile. Remove FE_IMAGE, FE_REPLICAS, FE_* resource vars. Simplify build/push/deploy to single IMAGE. Remove frontend.yaml k8s manifest. Remove provider integration test env vars (PROVIDER, PROVIDER_KEY, VENICE_API_KEY). Remove EXTRACTION_CONCURRENCY. Delete server/Dockerfile (backend-only image, superseded by root Dockerfile). Delete k8s/frontend.yaml (no separate FE deployment). Update ROADMAP: steps 5-7 and 9 marked complete. Step 8 (ICD) partial. Step 10 (smoke test + tag) is all that remains for v0.1.0. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
