fix: address review feedback for OpenCode reviewer integration

- Remove --copilot alias to avoid collision with existing Copilot concept
- Remove hardcoded model (-m) and variant flags; let user's OpenCode
  config determine the model, consistent with other reviewer CLIs
- Use generic "OpenCode Review" section header since model varies by config
