Overview

Package system defines the public contract for daemon-level operations in dployr.

It models system health, registration, installation/upgrade, domain requests, mode management, and instance lifecycle sync with base over WebSockets. The concrete implementation lives in internal/system; consumers should depend on the System interface defined here.
