Issue #38 — ci: Optimize Docker Build

Description

Bloated Docker images increase deployment times, consume excessive bandwidth, and expand the attack surface. Optimizing the Dockerfile ensures a lean, secure, production-ready artifact that only contains necessary runtime code.

---

Requirements & Context

Architectural Goal: Create an immutable, highly optimized deployment artifact.

Implementation Expectations: Refactor the existing Dockerfile to use multi-stage builds. Strip out devDependencies from the final image. Execute the Node process as an unprivileged non-root user.

---

Acceptance Criteria

• The final image size is drastically reduced.
• The container successfully runs the application without root privileges.

---

Out of Scope

• Multi-architecture builds (e.g., ARM64 + AMD64 configurations).

---

Suggested Execution

git checkout -b ci/docker-optimization

---

Suggested Commit Message

ci: optimize dockerfile for production sizes and security

---

Testing Notes

• Build the image locally and inspect its layers. Exec into the container and verify whoami is not root.

---

References

Definition of Done

• Ready for review.
