[BUG] Voice mode keybinding unresponsive on session start until toggled off/on

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Voice mode appears to be enabled by default when starting a new session,
but the recording keybinding (º key) does not respond until you toggle
voice mode off (/voice) and back on (/voice).

• Claude Code version: 2.1.74
• OS: Windows 11 Pro (10.0.26200)
• Shell: Git Bash
• Terminal: Windows Terminal

What Should Happen?

The voice recording keybinding should be functional immediately when
voice mode is active on session start, without requiring a manual toggle.

2. Press the voice recording key (º) — nothing happens
3. Run /voice — output says "Voice mode disabled" (confirming it was "on")
4. Run /voice again — output says "Voice mode enabled"
5. Now press º — recording works correctly
