Feature Request: Toggle-to-talk voice mode

Feature Request

Description

Add a toggle-to-talk option for voice mode alongside the existing push-to-talk. Instead of holding spacebar the entire time you're speaking, a single press would start recording and a second press would stop recording and submit.

Motivation

Push-to-talk works well for short commands, but for longer dictation (describing complex tasks, explaining context, etc.) holding the spacebar becomes uncomfortable. A toggle mode would make voice input much more ergonomic for extended use.

Proposed Solution

• Add a new keybinding action voice:toggleToTalk
• Single press starts recording (with a visual indicator that recording is active)
• Second press stops recording and submits
• Could be configurable in ~/.claude/keybindings.json
• Default could remain push-to-talk, with toggle-to-talk as an opt-in alternative

Alternatives Considered

• Using OS-level accessibility tools to simulate key holds — works but is hacky and unreliable
• External voice-to-text tools — loses the tight integration with Claude Code's voice mode
