Regression on Windows: /exit freezes Hyper and alacritty terminal and force-closes PowerShell in v1.14.19, but works in v1.14.18

[reimurashiki]

Description

After upgrading OpenCode from v1.14.18 to v1.14.19 on Windows, /exit no longer exits cleanly on some terminal hosts.

In v1.14.18, OpenCode exits normally.
In v1.14.19, Hyper Terminal freezes after /exit and must be ended from Task Manager. PowerShell standalone force-closes after /exit. Alacritty also reproduces the issue.

The issue does not happen in VS Code Terminal, and it also does not happen in Windows Terminal.

I already tested the following:

• Disabled plugins
• Updated Git for Windows
• Tested with both PowerShell and Git Bash for Windows
• Downgraded back to v1.14.18, where the issue disappears

This appears to be a regression introduced in v1.14.19.

OpenCode version

v1.14.19

Steps to reproduce

1. Install OpenCode v1.14.19 on Windows.
2. Open Hyper Terminal, PowerShell standalone, or Alacritty.
3. Launch opencode.
4. Start a normal session.
5. Run /exit.
6. Observe that the terminal freezes or force-closes.

Regression check:

1. Downgrade to OpenCode v1.14.18.
2. Repeat the same steps.
3. Observe that /exit works normally.

This should be fixed on latest

@EdwinStep can you please send a screen recording

[EdwinStep]

Huh, strange, can't reproduce anymore. Maybe it is not consistent. If I face it again, I'll send a recording.

This issue appears to be happening again on OpenCode v1.14.25 on Windows 11.
I retested the same scenario and /exit still causes terminal freeze / force-close on Hyper, PowerShell standalone, and Alacritty.
It still does not reproduce in Windows Terminal / VS Code Terminal.

Still happens for me in 1.14.31. Alacritty 0.17.0, pwsh 7.6.1, latest Windows 11

PS: happens (almost) every time for me.
