Hi everyone, I am new in the Databricks Asset Bundles world, so I need to understand how the .databricks directory works

1. I know that it is created when the databricks bundle deploy command is executed, and which is a place where metadata and the current state of a project is saved.

2.When I deploy using GitHub Actions, a GitHub virtual machine is enabled. This virtual machine clones the repository and executes the databricks command, which creates the .databricks directory locally, which now contains the current state of the deployed project. However, when the GitHub workflow finishes, everything is removed from the virtual machine, including the .databricks directory.

3. So, when I commit some updates to the repository and then deploy them with GitHub Actions, since the .databricks directory doesn't exist because the state of the VM is new, are the bundles deployed again? Is that how it works?, how I can update only the bundles instead re-deploy all?
