voiceEnabled setting doesn't activate voice mode on session start

Bug

The voiceEnabled: true setting in ~/.claude/settings.json does not actually activate voice mode when a new session starts. Hold-spacebar-to-record does nothing until you manually toggle voice off and on.

Steps to Reproduce

1. Set "voiceEnabled": true in ~/.claude/settings.json
2. Start a new Claude Code session
3. Hold spacebar — nothing happens (no recording indicator)

Workaround

Run /voice twice in each new session (toggles off then on). After that, hold-spacebar works normally.

Expected Behavior

Voice mode should be active on session start when voiceEnabled is set to true — no manual toggle needed.

Environment

• Claude Code 2.1.76
• macOS (Darwin 24.6.0)
• Terminal: Warp
• Microphone permissions confirmed working (voice works fine after manual toggle)
