hermes - 💡(How to fix) Fix [Bug]: CLI freezes after using /new command (WSL)

Bug Description

Using the /new command in an interactive Hermes session causes the terminal to become completely unresponsive. The prompt freezes and no further input is possible.

Steps to Reproduce

1. Start Hermes with hermes
2. Type /new (or /reset)
3. The terminal freezes immediately after confirming the command

Expected Behavior

The current session should be reset and a fresh session should start without any UI issues or freezing.

Actual Behavior

The terminal freezes completely after running /new. No further input is accepted until the process is killed.

Affected Component

CLI (interactive chat)

Messaging Platform (if gateway-related)

N/A (CLI only)

Operating System

0.15.0

Additional Logs / Traceback (optional)

Root Cause Analysis (optional)

The /new command calls new_session(), which performs heavy synchronous work (memory commit, multiple DB operations, memory manager hooks). Unlike /clear, it does not perform any prompt_toolkit UI reset (erase_screen, invalidate()) afterwards. This leaves the application in a broken state.

Proposed Fix (optional)

Extract the UI reset logic into a helper method _reset_cli_ui_after_session_change() and call it after both /clear and /new.
