Voice mode requires /voice toggle on every new session despite voiceEnabled: true

Description

Voice mode does not activate on new session start even though voiceEnabled: true is set in settings.json. The audio subsystem doesn't initialize — holding spacebar types spaces instead of recording.

Workaround: Run /voice (turns off) then /voice again (turns on) — this forces re-initialization and voice works for the rest of the session.

Steps to Reproduce

1. Set "voiceEnabled": true in ~/.claude/settings.json
2. Open a new Claude Code session
3. Hold spacebar → types spaces instead of activating voice recording
4. Run /voice → disables voice
5. Run /voice again → enables voice, now holding spacebar works correctly

Expected Behavior

Voice mode should be fully active on session start when voiceEnabled: true is in settings — no manual toggle needed.

Actual Behavior

• New sessions: spacebar types spaces (voice not initialized)
• Already-running sessions where /voice was toggled: spacebar works correctly
• Requires off/on toggle (/voice × 2) every new session

Environment

• OS: macOS (Darwin 25.1.0)
• Claude Code model: Opus 4.6
• Settings: "voiceEnabled": true confirmed in settings.json
• Microphone: Works fine after toggle — not a permissions issue

Additional Context

This happens consistently on every new session — not intermittent. The setting persists correctly in the config file, but the audio subsystem doesn't initialize from it on startup. The /voice toggle forces the initialization that should happen automatically.
