Feature: hotkey in agents view to open a new session without entering a prompt

Summary

When viewing the agents list (fleet view) in the terminal UI, there is no way to open a new session without first exiting and running claude again. A dedicated hotkey in the agents view to instantly start a new, empty session would streamline this workflow.

Motivation

Currently, starting a new session from the terminal requires:

1. Exiting the current session (Ctrl+D)
2. Running claude again

Some commands (e.g. /plugin) require a fresh session context, making this a repeated friction point. In the desktop agents view there is a + button for this, but no equivalent exists in the terminal agents list.

Proposed behavior

Add a hotkey (e.g. N or Ctrl+N) in the terminal agents/fleet view that opens a new, empty session — equivalent to running claude from scratch — without requiring the user to exit first.

Environment

• Claude Code CLI (terminal)
• Agents/fleet view (session list)
