Tool description/notes

Yesterday I ran into an issue with the Clay tool, and noticed that it doesn’t work at all with Depth Filter turned off. I assumed this was a bug, but searching Discord found a comment from Stephane pointing out that Clay requires depth filtering. That’s fine, of course, but it feels like the kind of info that should exist in the UI.

It seems like it would be helpful for tools to have an ‘info’ metadata field that can provide a brief description of the operation the tool performs and, if applicable, any caveats. This would go a long way to improving general usability for new users (and helping old users like me figure out what tools actually do, rather than just trying them and guessing).

Ideally, user-created tool copies could modify their descriptions as well (and maybe even include the description of the stock tool they’re based on).
