Model config openrouter/auto not reflected in TUI - config not being applied #15225

Description

Setting "model": "openrouter/auto" in the config file does not get reflected in the TUI. The TUI continues to show a different model (MiniMax M2.5 Free) as the current model, despite the config file being correctly loaded.

Steps to reproduce

1. Add the following to ~/.config/opencode/opencode.json:

{
  \"model\": \"openrouter/auto\",
  \"provider\": {
    \"openrouter\": {
      \"models\": {
        \"auto\": {}
      }
    }
  }
}

2. Start OpenCode TUI: opencode
3. Look at the bottom of the TUI - it shows MiniMax M2.5 Free, not openrouter/auto

Expected behavior

• The TUI should display and use the model specified in the config file
• OR the TUI should clearly indicate if it's overriding the config

Additional observations

1. CLI works: opencode run \"test\" -m openrouter/auto works and shows build · auto
2. Config loads: opencode debug config shows the model is being loaded correctly
3. Model in list: opencode models shows openrouter/auto at position 14
4. TUI search fails: Searching for "auto" in /models TUI returns no results
5. CLI flag error: Using -m openrouter/auto in TUI mode gives "error model openrouter/auto is not valid"

Environment

• OpenCode version: 1.2.10
• OS: Pop!OS (Linux)
• Provider: OpenRouter (with API key configured via /connect)

Suggested fix

Either:

• Make the TUI respect the config file model setting on startup, OR
• Allow -m openrouter/auto CLI flag to work in TUI mode (currently gives error), OR
• Make the model appear in TUI search so it can be selected interactively
