[Linux] Desktop app fails to start due to incorrect chrome-sandbox permissions

Description

OpenCode Desktop cannot start after installing the .deb package on Ubuntu.

Running:

ai.opencode.desktop

returns:

The SUID sandbox helper binary was found, but is not configured correctly.
You need to make sure that chrome-sandbox is owned by root and has mode 4755.

The issue is fixed by manually changing the permissions:

sudo chown root:root /home/maxh/ssd1/system_opt/OpenCode/chrome-sandbox
sudo chmod 4755 /home/maxh/ssd1/system_opt/OpenCode/chrome-sandbox

It seems the .deb installation does not preserve or set the required SUID permission for Electron's chrome-sandbox.

Environment:

• OS: Ubuntu 24.04.4 LTS (noble)
• OpenCode version: 1.18.15
• Package: opencode amd64 (.deb)
• Architecture: x86_64
