SDK interrupt: hosted sessions can report queued items they cannot recall

You'll notice
Useful2 Signal3
SDK

Hosted sessions can now list queued items they could not take back on interrupt.

What

The interrupt_cancel_queued_v1 capability description now says the still_queued list is "then empty" rather than always empty, and carves out hosted sessions, where a client lists there whatever it can no longer take back.

Details
  • The two cases named are a send already in flight to the session and the first prompt the session was created with.
Evidence

except that a client driving a hosted session lists there what it can no longer recall: a send already in flight to that session, or the first prompt the session was created with

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
