clone-into-existing-site

Converts an existing local WordPress Studio site's wp-content directory into a fresh clone of a GitHub repo while preserving the site's local runtime data (uploads, SQLite database, db.php drop-in, sqlite-database-integration mu-plugin, and all installed plugins and themes). Use when the user asks to "set up git on an existing site", "make this site's wp-content a git repo", "swap wp-content for <repo> on an existing site", "git-ify my Studio site's wp-content", "back the existing site with this repo", "point my local site at <repo>", "clone <repo> into an existing site without losing my uploads/database/plugins/themes", or describes any variant of converting an already-working local Studio site to be backed by a git repo. For brand-new sites with no local data to preserve, use clone-new-site instead.
