ci: add Dockerfile and Smithery config (#21)

This pull request introduces the following updates:

- **Dockerfile**: Introduces a Dockerfile to package the MCP for
deployment across various environments.
- **Smithery Configuration**: Adds a Smithery YAML file, which specifies
how to start the MCP and the configuration options it supports. It
allows you to [deploy](https://smithery.ai/docs/deployments) your MCP to
[Smithery](https://smithery.ai?utm_campaign=pr), serving it over SSE so
end-users do not need to install additional dependencies. To deploy,
merge this PR, then visit your [server
page](https://smithery.ai/server/mcp-proxy?utm_campaign=pr&modal=claim)
and click "Deploy" under the deployments page.

Please review these updates to verify their accuracy for your server and
feel free to customize it to your needs. Let me know if you have any
questions. 🙂
