Microphone and Submit buttons are too close together, causing accidental taps

Describe the bug

On the chat input form, the voice recognition (microphone) button and the submit (↑) button are positioned very close to each other. This makes it easy to accidentally tap the wrong button, especially on mobile devices.

Steps to reproduce

1. Open Claude Code chat on a mobile device
2. Type a message in the input field
3. Try to tap the submit (↑) button
4. Accidentally hit the microphone button instead (or vice versa)

Expected behavior

The two buttons should have enough spacing or visual separation to prevent accidental taps.
