Proposal: intent handover (login as + open resource) #799

Hi all,

I've opened a pull request with a first draft:
#798

The idea is to make it possible for applications to signal intent to one another, so that I can pass information to a receiving application with information about what my user wants to do. For instance, I want to be able to signal 'please log in as this user and open this resource' to a text editor application.

I've shown a working demo of this on the 2026 Solid Symposium and would like to see if we can get this type of handover defined as a specification for other app builders to implement.
