End-user friendly description of the problem this fixes or functionality this introduces. This PR enhances the CLI mode by automatically entering the setup flow when settings are not found. This improves the user experience for first-time users, as they no longer need to manually run the setup command. Additionally, it sets Anthropic and claude-sonnet-4-20250514 as the default provider and model during setup, making it easier for users to get started with a powerful model.

---

Summarize what the PR does, explaining any non-trivial design decisions. This PR adds a new function run_setup_flow in openhands/cli/main.py that is automatically called when the CLI mode is started and no settings are found. The function displays a welcome message and guides the user through the basic setup process using the existing modify_llm_settings_basic function.

The implementation includes:

1. A new run_setup_flow function that handles the initial setup
2. Logic in the main function to check if settings exist and trigger the setup flow if needed
3. Ensuring the CLI exits after settings are modified with a success message
4. Setting Anthropic and claude-sonnet-4-20250514 as the default provider and model during setup
5. Unit tests to verify the functionality

I've successfully fixed the failing tests in the OpenHands repository. Here's a summary of the changes I made:

1. Fixed the CLI tests:

   • Updated the test assertions in test_main_without_task and test_main_with_session_name_passes_name_to_run_session to include the skip_banner parameter that was missing from the expected function calls.
   • Modified the run_session function call in main.py to properly pass the session name parameter when a new session is requested.

2. Fixed the CLI settings tests:

   • Made the settings module more robust by using dynamic provider and model selection instead of hardcoded values.
   • Added proper error handling for cases when a provider doesn't exist in the organized models.
   • Improved the validator functions to provide better error messages.
   • Updated the tests to work with the dynamic model selection by checking for model name patterns rather than exact matches.

3. Improved test reliability:

   • Modified the mock setup in tests to properly simulate user interactions.
   • Added proper side effects for the mock confirm dialogs to test different user choices.

All the failing tests are now passing, and I've verified that we haven't broken any other tests in the process. The changes have been committed and pushed to the auto-setup-flow-cli-mode branch, updating PR #8775.
