Bug Description

/reset and /new slash commands freeze on Windows. After pressing Enter, an interactive
menu ("select 1/2/3") appears instead of a clean session restart. The menu is frozen — no
keyboard input is accepted. User must kill PowerShell and relaunch.

Steps to Reproduce

1. Start Hermes in PowerShell on Windows 11
2. Type /reset or /new and press Enter
3. Interactive menu appears — frozen, no input accepted
4. Must close PowerShell and relaunch

Expected Behavior

Immediate clean session restart with new session ID, no menu.

Actual Behavior

Routes through hermes reset CLI interactive menu path. prompt_toolkit input channel
appears closed at this point, causing deadlock.

Environment

• OS: Windows 11 / PowerShell / Windows Terminal
• Model: deepseek-v4-flash via sensenova custom provider
• Python: 3.12
