[Bug] Terminal lock when accessing /dev/tty* devices

[GlassOnTin]

Bug Description Claude code crashes / locks up the terminal any time it tries to directly access linux /dev/tty* or other similar devices. This seems to be a node.js bug but claude-code could defend against it too.

Environment Info

• Platform: linux
• Terminal: konsole
• Version: 2.0.76
• Feedback ID: e547637e-c4f5-4871-96f7-0c73771c294e
