[BUG] When model setting is "opusplan", Claude Code does not honor "--model" option when used with "--print"

What's Wrong?

When the setting via /model is opusplan, Claude ignores the --model setting when running with --print.

This only happens when the configuration is "opusplan". If I use /model to set the model to Default or sonnet then the command-line override works properly.

What Should Happen?

Claude should always use the --model setting when provided, even when the regular config setting is opusplan.
