Shift+Insert does not paste in OpenCode CLI inside VS Code terminal

Description

When running OpenCode CLI inside the VS Code integrated terminal, the Shift+Insert keyboard shortcut does not paste the current clipboard contents.

The same Shift+Insert shortcut works correctly when running OpenCode CLI in Windows Terminal.

Right-click paste works normally in VS Code; the issue is specifically with the Shift+Insert keyboard shortcut.

Expected behavior

Pressing Shift+Insert should paste the current clipboard contents into the OpenCode CLI input, consistent with the behavior in Windows Terminal.

Additional information

Shift+Insert works as expected when OpenCode CLI is run in Windows Terminal, but does not work when the same CLI is run inside the VS Code integrated terminal.

Right-click paste works in both environments, so this appears to be specifically related to handling the Shift+Insert keyboard shortcut in the VS Code terminal environment.
