[FEATURE] Voice mode: auto-send on spacebar release

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

When using voice mode, releasing the spacebar stops recording but still requires pressing Enter to send the message. This breaks the hands-free flow and makes voice input feel incomplete as an interaction mode.

Proposed Solution

Add a setting in Claude Code config that, when enabled, automatically submits the transcribed message as soon as the spacebar is released, no Enter press required.

Use Case Example

A developer dictates a question while their hands are on the keyboard for another task. They hold Space, speak, release and the message sends immediately, keeping them in flow without switching focus to press Enter.
