Phani/github-url-deploy-commands (#22)
<!-- mesa-description-start --> ## TL;DR Adds a `deploy github` subcommand to deploy applications directly from a GitHub URL, simplifying the deployment workflow. ## Why we made these changes This change allows users to deploy directly from a GitHub repository without needing a local copy of the code. This makes it faster and more convenient to deploy projects, especially in CI/CD environments or for quick tests. ## What changed? - **`cmd/deploy.go`**: Introduced the `deploy github` subcommand with flags for repository URL, Git ref, and entrypoint. This new command constructs a multipart HTTP request to the `/deployments` endpoint and streams deployment events back to the user. - **`go.mod`**: Updated dependencies to support the new deployment functionality. ## Validation - [x] Verified that `deploy github` successfully deploys a public GitHub repository. - [x] Tested with private repositories to ensure authentication with a GitHub token works correctly. - [x] Confirmed that invalid GitHub URLs are handled with clear error messages. <sup>_Description generated by Mesa.
