//! Agent process lifecycle: start, enable, disable, restart, and crash cleanup.
//!
//! [`AgentLifecycle`] owns the transitions for a single agent's worker process,
//! coordinating the database service and configured [`AppPaths`]. The free
//! functions are thin entry points that build a lifecycle for one operation;
//! the `operations` and `verification` submodules hold the spawn/teardown
//! logic and startup health-check probing.
