Team mode: selecting teammate with Enter in Ctrl+T panel accidentally sends auto-suggested message

Bug Description

In team mode, pressing Ctrl+T opens the teammate list panel:

╒═ team-lead · 103 tokens · shift + ↑/↓ to select
├─ @advisor: Idle for 36s · 0 tool uses · 124.8k tokens
├─ @coder: Idle for 36s · 20 tool uses · 59.2k tokens
├─ @coder-exp-9: Idle for 13s · 4 tool uses · 88.7k tokens
├─ @cr: Running Check llama70b health… · 2 tool uses · 58.0k tokens
├─ @mc: Idle for 36s · 4 tool uses · 117.8k tokens
└─ @reviewer: Idle for 36s · 3 tool uses · 115.9k tokens

Using Shift+Arrow to select a teammate and then pressing Enter correctly switches to the teammate view, but also sends whatever auto-suggested message was populated in the input field to the selected teammate.

Steps to Reproduce

1. Be in a team mode session with active teammates
2. Press Ctrl+T to open the teammate list
3. Use Shift+Up/Down to select a teammate
4. Press Enter to view their details
5. Observe: the view correctly switches to the selected teammate, but the auto-suggested next message in the input field is also sent to them as an unintended message

Expected Behavior

Pressing Enter while a teammate is selected in the Ctrl+T panel should only switch to that teammate's view, without sending any text from the input field.

Actual Behavior

Pressing Enter both switches the view (correct) and sends the auto-suggested message to the selected teammate (incorrect).
