CLI crashes on Windows when using Bun due to unresolved native inference binaries

[Mnnbnsl]

Describe the bug

When bootstrapping a standard AgentSession voice pipeline on Windows 10/11 x64 using the Bun runtime ecosystem (bun src/main.ts dev), the worker runtime crashes immediately during initialization when setting up inference.TurnDetector().

Even when explicitly attempting to set turnHandling.turnDetection: undefined, the underlying engine still defaults to warming up the lk_eot_audio engine, triggering a failure because Bun on Windows does not fetch or bind platform-specific native C++ Node addons (@livekit/local-inference-win32-x64-msvc) properly out of optional dependencies.

Changing the flag to the explicit string variant 'vad' bypasses it, but the default fallback state crashes out of the box when run with Bun.

Describe your environment

• OS: Windows 11 (x64)
• Runtime: Bun v1.3.14 (Windows x64 Native)
• Framework Packages: @livekit/agents (Latest JS SDK version)

Minimal reproducible example

1. Scaffold a fresh repository on a Windows machine.

2. Initialize dependencies using bun add @livekit/agents @livekit/plugins-ai-coustics livekit-server-sdk

3. Put down standard agent cli.runApp worker code containing turnDetection: new inference.TurnDetector().

4. Fire bun src/main.ts dev.
