Currently all of the examples for direct linking to custom assistants currently include a '&q=%s' which sends an empty query to the LLM. These should be adjusted to remove this unnecessary parameter. This can be found on both https://help.kagi.com/kagi/ai/assistant.html and https://help.kagi.com/kagi/ai/custom-assistants.html
Remove '&q=%s' from all examples so people are not creating empty prompts.
