using --prompt should wait for prompt configuration loading #7485

Description

when running opencode --prompt "heya", a different model may be used than running opencode and waiting a couple seconds and typing heya\n. the prompt submission triggered by the --prompt cli flag can happen before the full config processing has happened potentially resulting on usage of the wrong model.

Steps to reproduce

1. you may need to change your model in the tui depending on what is the default elsewhere. i had this issue with a preference for opus
2. run opencode --prompt "heya" and note the model used. it is a gemini for me
3. run opencode, wait for it to load, type heya and submit and note the model used. claude-opus-4-5 for me, as i intend.
