Task: Record first-deployment model and manual schema initialization

Identity

Apply two human decisions from 2026-08-14 to canonical memory and deployment documentation:
1. There is no production cutover: the first production deployment runs the ADR-003 split topology (Next.js frontend + Go backend) directly; no legacy production instance, no Node Worker in production.
2. Schema initialization is executed manually with the versioned SQL files; the ACK migration Job pod is not deployed.
Related: the first super administrator is created from ZHINIAN_BOOTSTRAP_ADMIN_* configuration at Go startup (implemented in task 20260814-go-bootstrap-admin-6e2b7d9c); legacy account import is not required.

Keep the versioned-SQL discipline (RDS-002); only the execution mechanism changes from the one-shot Job to manual execution.
Do not claim any production validation that has not happened.
Keep the migration Job manifest on disk, marked deprecated, for optional future automation.

Added DEP-001 to the decision index; moved ACK-001 to Superseded Decisions; amended RDS-002 execution detail; updated the ADR-003 status to "first production deployment pending".
Rewrote current-state.md Current Focus, Next Recommended Steps, Open Questions, and Risky Areas around the first-deployment model; recorded ff055c9 under Integrated Through.
Updated system-overview.md, module-map.md, and data-flow.md to describe the split-topology first deployment and manual schema initialization.
Updated commitments.md (dropped cutover obligations; added Go deployment artifacts, manual schema init, bootstrap config, and first-rollout validation commitments) and business-rules.md (manual schema execution rule; removed the moot cookie-compatibility question).
Updated deployment guidance in docs/DEPLOYMENT.md, README.md, and README.zh-CN.md to manual SQL execution and config-driven bootstrap; marked deploy/ack/migration-job.yaml deprecated with a header comment.

check_project_docs.py and check_doc_drift.py --task-id 20260814-deploy-model-reconcile-9b4c2e7f pass.
npm run deploy:check passes with the deprecated manifest comment in place.

Build the Go workload deployment artifacts (image, manifests, Ingress split) for the first production deployment.
Execute the manual schema initialization and role grants against the real RDS before the first rollout.
Decide whether to delete the deprecated migration-job.yaml later.
