[FEATURE] Feature request: Show voice mode status in status line

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

Currently, the status line JSON data does not include voice mode state. It would be useful to have a voice.enabled (or similar) field available so users can display whether voice mode is active in their custom status line scripts.

Proposed Solution

Add a voice.enabled boolean field to the JSON data passed to the status line script, e.g.:

{
"voice": {
"enabled": true
}
}
