Short answer: You can't.
Slightly longer answer: The only way to get even something "versionable" is to use the SDK and do a plugin export, there are 3: core-plugin, plugin (you'll only have that if Khoros PS did work for your community, you can't create that yourself) and studio-plugin, you'll be most interested in the studio plugin as it basically contains what you can edit in Studio. This is a folder with files that can be tracked via a git repo, but you can't (at least as far as I know) do any kind of deployment (especially not to production) with the SDK. The SDK exports stuff and then uploads/imports modified stuff onto your stage instance. Even though the entire deployment process Khoros uses (Studio Publish) is a git workflow behind the scenes, you do not have any control over that yourself other than using the Versions/Publishing sections within Studio and Admin (Prod) respectively.
