Add Docker Support

[Code42Cate]

Adds Docker containerization with multi-stage build using a distroless base image.

Also added it to server.json, not 100% if this is correct or how the release project here works. Would be great if this is automatically released to DockerHub. If you want any help with that lmk, happy to follow up with another PR or add it to this one.

I also moved @smithery/cli and playwright-core (only used for types) to devDependencies because it was bloating the Docker Image

Tested locally with Claude Desktop.

Greptile Overview

Summary

This PR successfully adds Docker containerization support using a multi-stage build pattern with a distroless Node.js base image for enhanced security and minimal size.

Key Changes:

• Multi-stage Dockerfile with builder and production stages
• Moved @smithery/cli and playwright-core to devDependencies (only used for types and tooling)
• Added Docker OCI registry configuration to server.json
• Comprehensive documentation in README with Docker setup and usage examples
• Proper .dockerignore to exclude unnecessary files from build context

Issue Found:

• Version mismatch: server.json uses 2.1.1 while package.json is at 2.1.2

Confidence Score: 4/5

• Safe to merge after fixing the version mismatch in server.json
• Docker implementation is solid with best practices (multi-stage build, distroless base, proper dependency optimization). Only issue is the version mismatch which should be corrected before merge to ensure consistency across registry configurations.
• server.json needs version update to match package.json (2.1.2)
