Crash on worktree session exit leaves terminal in broken state (Windows)

Description

Claude Code crashes when exiting/wrapping up a worktree session, leaving unreadable/garbled text in the terminal. The terminal appears to be left in raw mode or with incomplete ANSI escape sequences.

Steps to Reproduce

1. Start a Claude Code session on Windows
2. Use a git worktree flow during the session
3. When the session exits (or during worktree cleanup), Claude Code crashes
4. Terminal is left with strange unreadable characters

Expected Behavior

Session should exit cleanly, restoring the terminal to its normal state.

Actual Behavior

Claude Code crashes mid-exit, leaving the terminal in a broken state with garbled/unreadable text. Requires closing and reopening the terminal or running Reset-Host to fix.

Environment

• Claude Code version: 2.1.63
• OS: Windows 11 Pro for Workstations (10.0.26200)
• Shell: PowerShell
• Terminal: VS Code integrated terminal

Additional Context

This has happened multiple times, not just once. The crash appears to occur during the worktree cleanup/exit phase.
