Restructure CLI with Cobra

Replace custom switch-based routing with Cobra for cleaner command
hierarchy. Reorganize commands into logical groups:

- Root command handles deployment (--binary, --static, --domain, etc.)
- App management at top level: list, logs, status, restart, remove
- env subcommand group: list, set, unset
- host subcommand group: init, status, update, ssh
- Standalone: ui (renamed from webui), version

Add version command with ldflags support for build info.
