Right-click paste broken in Windows Terminal when CC is launched via FleetView (agent view)

Environment

• OS: Windows 11 + WSL2 Ubuntu
• Terminal: Windows Terminal
• Claude Code launched via FleetView / agent view (multi-agent UI)

Steps to reproduce

1. In Windows Terminal (WSL Ubuntu), launch CC directly via claude → right-click in the prompt area pastes clipboard contents (Windows Terminal's native right-click paste). ✅ Works.
2. In the same terminal, launch CC via FleetView / agent view → right-click does nothing. ❌ Broken.

Suspected cause

FleetView enables xterm mouse tracking (likely \e[?1000h / ?1006h) so it can handle its own pointer interactions (clicking agents in the list, scrolling, etc.). With mouse tracking on, mouse events are forwarded to the application instead of being handled by the terminal emulator, so Windows Terminal's right-click paste menu never fires.

Plain claude doesn't enable mouse tracking, which is why the same terminal works fine there.

Request

One of:

1. Release mouse capture while the input prompt is focused / idle, so the terminal can still handle right-click paste; or
2. Add a setting to disable FleetView's mouse capture for users who'd rather use terminal-native mouse behavior.

Right-click paste is a deeply ingrained habit in Windows Terminal — losing it inside FleetView is a meaningful UX regression vs. plain CC.
