add some common client actions to standard catalog

Propose adding copyToClipboard and possibly confirm (opens standard confirmation box)

I think copyToClipboard makes sense! I'm not so sure about confirm seeing as that should already be possible to implement via modal, and if it isn't, then we should make it so.

Can we do this in a custom catalog for now and then add it for v0.10?

This seems like something that could just be implemented in a client's component without it needing to be part of A2UI.

It also seems a little odd for an agent to have control over what is in a client machine's clipboard. I mean, it's not technically a privacy issue since it can't read the contents, but it feels like something that wouldn't be expected by the user.

A custom component could easily implement this on the client side if the intention is to have a "copy to clipboard" button. Same with the "confirm" box.

What's the actual use case here?

Let me close this, agree they don't belong in the standard catalog.

I started a thraed in chat about making an a2ui-contrib github repo for common functionality like this that doens't belong in the basic catalog, can follow up there
