Feature: Add SenseVoice/FunASR as offline STT option

[LauraGPT]

Motivation

Jarvis is an offline voice assistant in Rust that respects privacy. FunASR (16K+ stars) provides models that can run offline via multiple Rust-friendly integration paths.

Integration Options for Rust

1. Sherpa-ONNX (C API callable from Rust): Runs SenseVoice and Paraformer models natively

   • GitHub: https://github.com/k2-fsa/sherpa-onnx
   • Has Rust bindings potential via C FFI

2. SenseVoice.cpp (pure C/C++): Direct integration via FFI

   • GitHub: https://github.com/lovemefan/SenseVoice.cpp

3. ONNX Runtime (Rust crate ort): Load SenseVoice ONNX model directly

   • Model: funasr/sensevoice-small-onnx on HuggingFace

Why SenseVoice

• 234M params: Small, fast, efficient
• Non-autoregressive: Deterministic latency
• 50+ languages with auto detection
• Fully offline: No network needed
• Built-in VAD: Included in model pipeline
