//! Voice pipeline integration (D-138, Spike 2).
//!
//! Translates culture-neutral semantic base text into character-voiced output
//! via an LLM re-voicing pipeline. The pipeline is a background runtime
//! enhancement — the game is complete and functional without it.
//!
//! ## Components
//!
//! - `prompt_builder` — composition engine: NPC data + culture + tell state → prompt string
//! - `cache` — MessagePack voice cache (store/retrieve, length-gated variants)
//! - `queue` — crossbeam work queue with priority + backpressure
//! - `worker` — inference worker pool (dynamic scaling, owns sr-voice HTTP clients)
//! - `hardware` — hardware detection + dynamic sr-voice instance management
