interrupt - interruptible multi agent hook interface

[pgrayy]

Description

Update the _Interruptible interface to support multi agent hooks. Specifically, we need to have the interrupt method look for the source field, which is where multi agent hook events store a reference the the multi agent instance.

Also, as a convenience, I am adding user responses to the interrupt state context on resume. This is particularly useful for Swarm and Graph, which have some unique handling of the task prompt that makes it a bit more challenging to get a reference where needed. This is a bit confusing yes, but when https://github.com/strands-agents/sdk-python/pull/1193/files is ready, it will become more clear.
