Allow iframes to deal with tools in their parent/top-level context

[yoavweiss]

As discussed in #51 , in-page agents may be better off if their are not "in-page" and are able to be spun off to an iframe.

Similarly, it might be good to enable iframes to expose tools to the parent page, so that a single agent can have context from the entire page surface that the user is seeing.

What if we had a way for an iframe to say "I want to register a tool with my parent (or top-level) frame", and the parent had a permission policy that allowed iframes to do that? Wouldn't that be neat? :D

Once #51 settles, it'd be similarly neat to have the iframe be able to execute tools on the parent/top-level, provided similar permissions.

Agreed! Do you think this is covered by #57 @yoavweiss?

+1 this seems like a dupe of #57 :)

#57 is half of it. Once #51 (comment) lands, exposing that to iframes (with explicit permission from the parent) would be the other half.
