Replit

Build me a personal cloud dev environment to replace Replit, on a VPS I already have. Requirements: - code-server (VS Code in the browser) behind Caddy with HTTPS and basic auth, installed by one setup script. This is assembly of good parts, not a new IDE. - A `dev new <name> --template node|python|static` CLI that copies from a templates/ folder (each with .gitignore, README stub, and a run script) into ~/projects/<name> and runs git init. - Each project gets a port in projects.json; Caddy routes <name>.dev.mydomain.com to it, so anything I run is instantly viewable at a URL. - `dev deploy <name>` commits and restarts the project's systemd user service; `dev logs <name>` tails it. - Per-project secrets in <project>/.env, never committed; the template .gitignore enforces it. - Nightly tarball of ~/projects to a backups/ folder, keep 7. - Reachable only over HTTPS with auth (bind to a VPN interface instead if one exists); no telemetry. - Out of scope: multiplayer editing, hosted AI agents, and per-project containers. One VPS, one user, my own projects. - README: the wildcard DNS record, Caddy config, and code-server auth setup.
