//! Lifecycle hooks for prompts and automatic tool execution.
//!
//! Handlers run in registration order until one returns `Some(HookDecision)`.
//! Return `None` to let later handlers run, including audit handlers.
//!
//! `UserPromptSubmit` runs in [`Client::send`](crate::Client::send). Pre- and
//! post-tool hooks run only during automatic tool execution. Each event owns a
//! structured conversation-history snapshot; post-tool history includes the
//! unmodified result. Handle fallible work inside a hook and choose a decision;
//! hook futures return `Option<HookDecision>`, not `Result`.
