[FEATURE] Feature request: expose voice mode state in status line data

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

The status line JSON data currently does not include the voice mode state, making it impossible to show a voice mode indicator (e.g. a microphone icon) in custom status line scripts.

When using voice mode alongside a custom status line, there's no visual indicator of whether voice mode is active. This is especially useful when toggling voice on/off during a session — a quick glance at the status line should confirm the current state without needing to check /voice.

Proposed Solution

Add a field like voice.enabled (boolean) to the JSON object passed to the status line script, alongside existing fields like model, context, git.branch, etc.

This would allow status line scripts to render something like:

claude-opus-4-6 | 12% ctx | main | 🎤 voice

Alternative Solutions

Parsing ~/.claude/settings.json for voiceEnabled is possible but only reflects the configured preference, not the live runtime state (e.g. if toggled mid-session via /voice).
