Why does the Computer protocol not have the goto method?

Describe the feature

Right now, the computers you create can't define (or use) the goto method to go to a specific URL. This means that if you are at a page that is not a search engine, it is hard to go to a completely different page, unless the link to the said page is on the current page.

The BasePlaywrightComputer class still defines the goto method but since this is not part of the Computer protocol, the agent doesn't use it. Am I missing something or this protocol missing an important function?

It's not part of the base CUA protocol: https://platform.openai.com/docs/api-reference/responses/object#responses/object-output-computer-tool-call-action

That said, we should indeed make the Computer extensible. Rather than adding goto, we should allow arbitrary additional actions to be exposed by the Computer.

PR welcome, or else I can get to it at some point!
