//! Plugin validate command.
//!
//! Responsibilities:
//! - Re-validate discovered plugin manifests.
//! - Confirm declared runner/processor executables resolve inside the plugin directory.
//!
//! Not handled here:
//! - Plugin installation, uninstall, or scaffolding.
//! - Registry enablement decisions.
//!
//! Invariants/assumptions:
//! - Discovery already performed baseline manifest parsing before this command runs.
//! - Validation must fail fast on missing referenced executables.
