Windows Command Prompt Mouse/Scroll Events Misbehave After Exiting "opencode" #12434

Description

While using opencode from the Windows Command Prompt (cmd.exe), the terminal starts behaving incorrectly after opencode is closed or exited.

Once the opencode process terminates, the Command Prompt does not properly restore its original input state. As a result, mouse-related interactions become unstable, including:

Mouse scrolling behaves erratically or stops working correctly

Mouse movement triggers unexpected behavior

Cursor positioning becomes inconsistent when interacting with the terminal

This issue persists for the current Command Prompt session and typically requires closing and reopening the terminal to restore normal behavior.

The problem appears to be related to opencode not fully resetting the terminal/console state on exit, particularly around mouse or input handling on Windows.
