add deployment workflows to auto-deploy docker container & npm package

[zudsniper]

HOW TO USE

1. set these github secrets:

NPM_TOKEN
DOCKERHUB_USERNAME
DOCKERHUB_TOKEN

*note that dockerhub repository with the appropriate name matching this repository must have been MANUALLY created already for this to work (which, is kinda dumb. but it is the case at the moment.)

2. then create a release branch and push to it. that should do it. if you have issues let me know, i can fix them -- I just didn't want to test it with my npm tokens and dockerhub tokens since I don't want to take credit for your work. if you don't test the PR for a little while, then I probably will, just because I'd like to use this mcp server easily--but if I do, when you get around to merging / implementing yourself if you want to for some reason, just tell me and I'll get rid of mine.

Cheers,
Jason

AI SUMMARY OF CHANGES

feat(ci): Implement automated release and deployment workflow

This PR introduces a comprehensive CI/CD pipeline to automate the entire release process, from versioning to publishing on npm and Docker Hub.

Key Changes:

• Automated Release Workflow (.github/workflows/release.yml)

  • Triggers on a push to the release branch.
  • Validates that the version has not already been published to npm.
  • Runs tests to ensure code quality.
  • Publishes the package to npm as @democratize-technology/claude-code-container-mcp.
  • Builds and pushes three multi-platform (linux/amd64, linux/arm64) Docker images.
  • Creates a GitHub Release with an automatically generated changelog from commit history.

• Docker-Only Update Workflow (.github/workflows/docker-update.yml)

  • Triggers when Docker-related files are changed on the main branch.
  • Builds and pushes dev-tagged Docker images, allowing for quick updates without a full version release.

• Release Helper Script (scripts/prepare-release.sh)

  • An interactive script that guides the user through preparing a new release.
  • It handles version bumping, CHANGELOG.md updates, and creates and pushes the release commit to trigger the workflow.

• Comprehensive Documentation

  • docs/SETUP_DEPLOYMENT_WORKFLOWS.md: A new, detailed guide on setting up the required secrets (NPM_TOKEN, DOCKERHUB_USERNAME, DOCKERHUB_TOKEN) and using the new workflows.
  • README.md: Updated to prioritize npm as the primary installation method, improve configuration examples, and add sections on the development and release process.
  • RELEASE.md: Updated to reflect the new automated release process while keeping manual steps as a fallback.

How to Use:

1. Configure the required repository secrets as detailed in the new setup documentation.
2. Run the helper script: ./scripts/prepare-release.sh.
3. Follow the interactive prompts. The script will push to the release branch, and the GitHub Action will automate the rest.

This automation significantly streamlines the release process, reduces the potential for manual error, and ensures consistent, versioned deployments.
