Finish updating README for the project, finish setting docker for the project

[Boxuan-Matty-Lin]

This pull request introduces Docker support for both development and production environments, updates documentation to reflect the new workflows, and makes minor configuration improvements for deployment. The main changes are the addition of multi-stage Docker builds, Docker Compose files for different environments, and comprehensive updates to the README.md for onboarding and deployment instructions.

Dockerization and Deployment:

• Added a multi-stage Dockerfile with separate stages for development, build, and production runtime, optimizing for image size and security.
• Introduced .dockerignore to exclude unnecessary files and directories from Docker build context, reducing image size and improving build times.
• Added compose.dev.yml for local development with hot reloading and bind mounts, and compose.production.yml for production deployment using the optimized runtime image. [1] [2]

Documentation and Onboarding:

• Rewrote and expanded README.md to include detailed instructions for local development, Docker-based workflows, production deployment, and testing.

Configuration Improvements:

• Updated next.config.ts to enable Next.js standalone output, ensuring compatibility with Docker production builds.

pnpm version 9.12.0 is hardcoded in multiple stages (lines 6 and 23). Consider defining it as a build ARG at the top of the Dockerfile to maintain consistency and simplify version updates.
