Docker Support with Bun Runtime

This PR adds optional Docker support for delphitools using Bun for self-hosting option based on the opened Issue -> #22

Added

• Dockerfile: multi-stage build
  • deps: bun install
  • builder: Next.js build
  • runner: minimal production image
• docker-compose.yml: port mapping, resource limits, health checks, restart policy, security hardening
• .dockerignore: smaller build context

Usage

docker-compose up -d
docker-compose logs -f app
docker-compose down
docker-compose up -d --build

Test Validation

• Image builds successfully
• Container runs and responds
• Health checks pass
• App works on localhost:3000

Summary

This keeps Docker as an optional deployment method while preserving the app’s local, private, static design.

Based on Bun best-practices documentation source: https://bun.com/docs/guides/ecosystem/docker
