[BUG] Voice mode doesn't activate on first session start — requires disable/re-enable cycle

What's Wrong?

Component: Voice mode

Description:
When voice mode is enabled at session start, pressing spacebar inserts a space
character instead of starting audio recording. The feature only works correctly
after manually disabling and re-enabling voice mode within the same session.

Environment:

• Claude Code version: 2.1.80
• Platform: Windows 11 Pro
• Shell: bash

What Should Happen?

Expected Behavior:
Voice mode should be fully functional immediately on session start without
requiring a toggle cycle.

5. Press spacebar — recording now works correctly
