Although the autocomplete feature is of great help, some websites might not want their users to use it in specific web pages.

Example:
if a user uses autocomplete superpowers in websites like codewars, leetcode or LiveCodes code challenges (specially if the time factor is important), it might be considered as cheating :)
However, if the same website uses the editor in code tutorials, it might be desirable to enable the autocomplete.

My suggestion:

If a web page includes this meta tag, the autocomplete should not be activated in this specific web page even if the domain is in the allowlist:

<meta name="codeium:type" content="none">

I expect if site owners have control over when to enable/disable the autocomplete, more websites are more likely to endorse it and tell the users about it (even as a feature).

If you agree to this approach, I can open a PR with the implementation, including the option to restrict injection type by the value of the content attribute as mentioned here: #29 (review)
