[BUG] /voice fails on Windows native install — "native audio module could not be loaded"

Bug description

Running /voice in Claude Code on a native Windows install fails immediately with:

Voice recording requires the native audio module, which could not be loaded.

No additional error details, stack trace, or guidance on how to resolve the issue is provided.

Environment

• OS: Windows 11 Pro 10.0.26200
• Claude Code: 2.1.69
• Node.js: v22.20.0
• Install method: Native Windows install via irm https://claude.ai/install.ps1 | iex
• Shell: Git Bash

Steps to reproduce

1. Install Claude Code on Windows via irm https://claude.ai/install.ps1 | iex
2. Open a terminal and run claude
3. Type /voice
4. Observe the error message

Expected behavior

Voice mode should activate and allow microphone input, or provide actionable error messages (e.g., missing dependencies, unsupported platform).

Additional context

• No native audio dependencies (PortAudio, Sox, etc.) are documented as prerequisites for Windows
• The error message doesn't indicate whether this is a missing build dependency, a platform limitation, or a packaging issue
• Would be helpful if the error included guidance on what's needed to fix it
