Adding llm provider to set when is checked to not repeat the same check

[fscheu]

The function llm_api_check inside core\cli\main.py checks if the configured LLMs are reachable.
As some LLM could be repeated in the configuration, there is a set variable to check if the LLM was already checked, but inside the for loop, the code never add the LLM to the set when is checked.
The last line is what I'm adding in this PR

    checked_llms: set[LLMProvider] = set()
    for llm_config in config.all_llms():
        if llm_config.provider in checked_llms:
            continue

        client_class = BaseLLMClient.for_provider(llm_config.provider)
        llm_client = client_class(llm_config, stream_handler=handler, error_handler=handler)
        try:
            resp = await llm_client.api_check()
            if not resp:
                success = False
                log.warning(f"API check for {llm_config.provider.value} failed.")
            else:
                log.info(f"API check for {llm_config.provider.value} succeeded.")
                checked_llms.add(llm_config.provider)

You could wrap these calls in try-except blocks to ensure that errors are properly logged and don't crash the app.

try:
success = await orca.run()
except Exception as e:
log.error(f"Error running orchestrator: {str(e)}")
success = False

Hi @RahulVadisetty91
I'm new to making pull requests, so I wanted to know if I need to apply your comment to advance with the approval.

I've seen that the code has been fully rewritten so this PR no longer sense.
