Added export to GitHub functionality similar to Lovable.dev

Key Features

• Connect any project to GitHub and it automatically creates a new repo and pushes the code.
• After each follow-up prompts, when new files are created/updated, it again automatically pushes the code changes to that repo.

OAuth App was created so that the users can authorize and gives the permission to create repos and push code changes.

Register OAuth App

• Replace <BASE_URL> with the actual deployed frontend URL (or) http://localhost:3000 for local testing.
• After creation, we will get GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET. Save these in the environment variables files using .env.example file of frontend and primary-backend. We need both of them on the primary-backend and we need only GITHUB_CLIENT_ID in the frontend.

Currently, there is an issue with projects. All projects use the same directory for creating/updating the files. For example, all projects of React type, use /tmp/react-app directory to make changes. Hence, there is not separate directory for a new project. Each project, should be at a unique path. For instance, when a new project is created of Next.js type, the base code of Next.js project should be copied from /tmp/next-app to let's say /app/<projectId>.

When the above issue is fixed, then, when we are pushing the code to GitHub using pushToGitHubFromDockerContainer(...), we have to give the path to that particular project as the third parameter in the function. For now, I am passing /tmp/projectType as the project directory.

This PR also includes some minor changes/fixes in worker and ws-relayer.

Hi abhignakumar, can we connect.

Hi abhignakumar, can we connect.

Sure.

this is good

so eventually user containers are running as a pod on a k8s cluster. This will not with there altho a decent approach to test things locally

[abhignakumar]

Okay.
Yeah, as the project code was inside the code-server docker container, I had to implement it, in this way. (And to test locally)

this is good

Thank you!
