voiceEnabled setting in settings.json doesn't persist across sessions

Description

voiceEnabled: true is set in ~/.claude/settings.json, but voice mode does not auto-enable when starting a new chat session. Users must manually run /voice at the start of every conversation to activate it.

Expected behavior

If voiceEnabled: true is set in settings.json, voice mode should be active automatically when a new session starts -- no need to toggle it manually each time.

Current behavior

• voiceEnabled: true exists in ~/.claude/settings.json
• Starting a new chat requires running /voice to enable voice mode
• Voice mode disables itself after each session ends
• The setting appears to have no effect on session initialization

Additional context

• There's also no --voice CLI flag to launch with voice enabled
• The /voice command works fine within a session -- the issue is purely about persistence across sessions
• Voice key binding (Space, hold-to-record) is not customizable either, but that's a separate feature request

Environment

• macOS (Darwin 25.3.0)
• Claude Code CLI
