Add newproject command and fix template bugs

- Add newproject, ssh, templates commands for full project scaffolding
- Add homelab SSH, Caddy, port, and proxy_host fields to Config
- Fix dotEnvExample: use container-internal port (3000/8000/8080) not host port
- Fix caddySnippet: use configurable proxy_host instead of localhost
- Fix dockerComposeTemplate: add build: path so image-less deploys work
- Commit gtea.exe binary
