//! # gpty-ai
//!
//! Pluggable AI backends for gpty's Inspector pane.
//!
//! ## Backends
//!
//! | Kind | Crate module | Role |
//! |------|--------------|------|
//! | [`BackendKind::Mock`] | [`mock`] | Offline / tests — deterministic Markdown |
//! | [`BackendKind::Omp`] | [`omp`] | Oh-My-Pi via `omp --mode rpc` |
//! | [`BackendKind::Cli`] | [`cli`] | Any CLI via a subprocess NDJSON bridge |
//!
//! Future: OpenAI-compatible HTTP, Anthropic, other harnesses (ACP, print mode).
//!
//! Each Godot bridge owns one private [`AiSession`]. A session keeps one
//! backend process alive across sequential prompts and exposes bounded,
//! correlated event envelopes for polling.
