opentui: fatal: Object.entries requires that input parameter not be null or undefined

Bug Description

When running opencode, I encountered a fatal error related to Object.entries receiving null or undefined input in the theme resolution code.

Error Stack Trace

TypeError: Object.entries requires that input parameter not be null or undefined

Steps to Reproduce

1. Run opencode command
2. Error occurs during theme resolution

Environment

• opencode version: 1.2.27

Analysis

The error occurs in resolveTheme function, suggesting that a theme object is null/undefined when passed to Object.entries. This could be caused by:

• Missing theme configuration
• Theme not properly initialized before use
• Invalid theme value being passed

Expected Behavior

The application should handle null/undefined theme values gracefully, either with a default fallback or proper error message.
