//! Supervisor tests: verify proxy respawn logic and state file updates.
//!
//! These tests exercise the supervisor's detection of dead proxy handles and the
//! state file update path. We don't spawn real ccs-proxy instances; instead we
//! test the deduplication logic, LifecycleConfig construction, and state file
//! mechanics that the supervisor depends on.
