//! Parakeet (NVIDIA) transcription backend for streaming local speech recognition.
//!
//! Feature-gated behind `local-parakeet`. Currently a stub — implementation planned.
//!
//! Parakeet offers 160ms chunk processing with end-of-utterance detection,
//! making it the lowest-latency local option. Native Rust crate, no C dependency.
